In Triangle Abc , Side BC Is 3 Inches Long And Side AB Is 16 Inches Long. Angle A Measures 20 . Given

Answers

Answer 1

Answer:

Angle C is 101 degrees

Step-by-step explanation:

Given triangle ABC,

Side BC =3

Side AB =16

Angle A=20

Also, Angle C is an obtuse angle.

To find Angle C:

As shown in figure,

By using basic trigonometry,

Angle A =20 and AB=13

BD =13sin20 and AD = 13cos20

Now, AD=AC+CD

CD=13cos20-3

CD=2.30506

And BD =13sin20=11.86828

In triangle BDC,

Tan(BCD) = [tex]\frac{BD}{CD}[/tex]

Tan(BCD) = [tex]\frac{11.86828}{2.30506}[/tex]

Tan(BCD) = [tex]\frac{11.86828}{2.30506}[/tex]=5.1487

Angle BCD = 79.00

Therefore, Angle BCA =180-Angle BCD=180-79=101.

Angle C is 101 degrees

In Triangle Abc , Side BC Is 3 Inches Long And Side AB Is 16 Inches Long. Angle A Measures 20 . Given
Answer 2

The measure of angle C in triangle ABC is approximately 150.8° when rounded to the nearest tenth of a degree.

To find the measure of angle C, we can use the fact that the sum of the angles in any triangle is 180°. Given that angle A is 20° and angle C is obtuse, we can set up the following equation:

[tex]\[ \angle A + \angle B + \angle C = 180 \][/tex]

Since angle A is 20°, we can substitute this value into the equation:

[tex]\[ 20 + \angle B + \angle C = 180 \][/tex]

To find the measure of angle B, we can use the Law of Sines, which states that the ratio of the length of a side of a triangle to the sine of the angle opposite that side is the same for all three sides of the triangle:

[tex]\[ \frac{a}{\sin(\angle A)} = \frac{b}{\sin(\angle B)} = \frac{c}{\sin(\angle C)} \][/tex]

We can use the sides AB and BC to find angle B:

[tex]\[ \frac{16}{\sin(20)} = \frac{3}{\sin(\angle B)} \][/tex]

Solving for[tex]\(\sin(\angle B)\)[/tex]:

[tex]\[ \sin(\angle B) = \frac{3}{16} \cdot \sin(20) \][/tex]

Now, we calculate the value of [tex]\(\sin(\angle B)\)[/tex]:

[tex]\[ \sin(\angle B) = \frac{3}{16} \cdot \sin(20) \approx \frac{3}{16} \cdot 0.3420 \approx 0.0649 \][/tex]

Taking the inverse sine [tex](sine) of \(\sin(\angle B)\)[/tex] gives us the measure of angle B :

[tex]\[ \angle B = \sin(0.0649) \approx 3.7 \][/tex]

Now we have the measures of angles A and B, so we can find angle C :

[tex]\[ 20 + 3.7 + \angle C = 180 \] \\[/tex]

[tex]\[ \angle C = 180 - 20 - 3.7\] \\[/tex]

[tex]\[ \angle C = 180 - 23.7 \] \\[/tex]

[tex]\[ \angle C = 156.3 \][/tex]

Since angle C is obtuse, we do not need to consider any other solutions for angle B that might be less than 90°. Therefore, the measure of angle C is approximately 156.3°, which rounds to the nearest tenth of a degree as 150.8°.

There was a bowl with 120 candies in it. Billy, Bob and Buck found the bowl. Billy ate 2/12 of the candies, Bob ate 3/12 and Buck had 5/12. How many candies were left?

Answers

Final answer:

Billy ate 1/6, Bob ate 1/4, and Buck ate 5/12 of the candies. To find the number of candies left, subtract the total fraction eaten from the total.

Explanation:

To find out how many candies were left, we need to subtract the candies that Billy, Bob, and Buck ate from the total number of candies in the bowl.

Billy ate 2/12 of the candies, which is equivalent to 1/6 of the candies because 2/12 can be simplified to 1/6.

Bob ate 3/12 of the candies, which is equivalent to 1/4 of the candies because 3/12 can be simplified to 1/4.

Buck ate 5/12 of the candies.

To find the total fraction of candies eaten, we add the fractions: 1/6 + 1/4 + 5/12. The common denominator for these fractions is 12.

Converting all the fractions to have a denominator of 12, we have: 2/12 + 3/12 + 5/12 = 10/12 = 5/6.

So, the three boys ate 5/6 of the candies.

To find the number of candies left, we subtract 5/6 from the total number of candies in the bowl:

120 - (5/6 * 120) = 120 - (5/6 * 120/1) = 120 - (5 * 120/6) = 120 - 100 = 20.

Therefore, there are 20 candies left in the bowl.

line m contains the points -3,4 and 1,0. write the equation of a line that would be perpendicular to this one and pass through the point -2,6 answer for algebra 1 need help

Answers

The equation of line perpendicular to line containing points (-3, 4) and (1, 0) and passes through (-2, 6) in point slope form is y = x + 8

Solution:

Given that line m contains points (-3, 4) and (1, 0)

We are asked to find the equation of line perpendicular to line containing points (-3, 4) and (1, 0) and passes through (-2, 6)

Let us first find slope of the line "m"

Given two points are (-3, 4) and (1, 0)

[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

[tex]\left(x_{1}, y_{1}\right)=(-3,4) \text { and }\left(x_{2}, y_{2}\right)=(1,0)[/tex]

[tex]m=\frac{0-4}{1-(-3)}=-1[/tex]

Thus slope of line m is -1

We know that product of slope of given line and perpendicular line are always -1

So, we get

[tex]\begin{array}{l}{\text { slope of line } m \times \text { slope of perpendicular line }=-1} \\\\ {-1 \times \text { slope of perpendicular line }=-1} \\\\ {\text { slope of perpendicular line }=1}\end{array}[/tex]

So we have got the slope of perpendicular line is 1 and it passes through (-2, 6)

Let us use the point slope form to find the required equation

The point slope form is given as:

[tex]y - y_1 = m(x - x_1)[/tex]

[tex](x_1, y_1) = (-2, 6)[/tex] and m = 1

y - 6 = 1(x - (-2))

y - 6 = x + 2

y = x + 8

Thus equation of required line in point slope form is y = x + 8

the height of a triangle is 7 cm greater than the base. the area of the triangle is 147 square centimeters. find the length of the base and the height of the triangle​

Answers

Answer:

height is 21cm and the base is 14cm

Step-by-step explanation:

Take a look at the equation for the area of a triangle [tex]A = \frac{bh}{2}[/tex]

Write "height of a triangle is 7 cm greater than the base" as an equation:

h = b + 7

Substitute h and the area of the triangle, 147 into the equation for area.

[tex]A = \frac{bh}{2}[/tex]

[tex]147 = \frac{b(b+7)}{2}[/tex] distribute over brackets

[tex]147 = \frac{b²+7b)}{2}[/tex]  get rid of fractions

[tex]147*2 = b²+7b[/tex]

[tex]294 = b²+7b[/tex]

Rearrange to standard for for quadratic equations

0 = b²+7b - 294

standard form is 0 = ax² + bx + c

In this base, the x variable is replaced by "b".

Use the quadratic formula to solve for b. Substitute the other three values.

[tex]x = \frac{-b ±\sqrt{b^{2}-4ac} }{2a}[/tex]

[tex]x = \frac{-(7) ±\sqrt{7^{2}-4(1)(-294)} }{2(1)}[/tex] Simplify

[tex]x = \frac{-7 ±\sqrt{1225} }{2}[/tex]

[tex]x = \frac{-7 ±35 }{2}[/tex]

Split the equation at ±

[tex]x = \frac{-7 +35 }{2}[/tex]

[tex]x = \frac{28}{2}[/tex]

[tex]x = 14[/tex]  <=base

[tex]x = \frac{-7 -35 }{2}[/tex]

[tex]x = \frac{-42}{2}[/tex]

[tex]x = -21[/tex]  <=We know this number is not possible, so its inadmissible.

The base is 14 cm.

Substitute base = 14 in h = b + 7

h = b + 7

h = 14 + 7

h = 21

The height is 21cm.

Therefore, the height is 21cm and the base is 14cm.

Final answer:

The teacher purchased 11 packets of tests for the math competition.

Explanation:

The question is about calculating the number of test packets Andrew's teacher purchased for the math competition. We know that there was a basic enrollment fee of $30, and each packet of 10 tests cost an additional $11. The total cost was $151. To find out how many test packets the teacher purchased, the first step is to subtract the enrollment fee from the total amount spent. Therefore, $151 - $30 = $121 was spent on test packets.

Then, we divide this amount by the cost of each test packet. So $121/$11 gives us 11. Hence, the teacher purchased 11 packets of tests for Andrew's math competition.

Math problem: a light-blocking screen transmits 18% of the light and reflects back the rest. how much light is transmitted through 2 screens?

Answers

Step-by-step explanation:

Paolo's expression 3(x+2)+3

Final answer:

To find how much light is transmitted through two screens that each transmit 18% of the light, multiply 18% by itself (0.18 x 0.18), which results in 3.24% of the original light being transmitted through both screens.

To determine how much light is transmitted through two light-blocking screens, we need to calculate the percentage of light that makes it through both screens. The first screen transmits 18% of the light. This means that only 18% of the initial light intensity will pass through the first screen.

When the light that has passed through the first screen encounters the second screen, again only 18% of that light will be transmitted. To find the total amount of light transmitted through two screens, we multiply the transmission rates of each screen:

Transmitted light through two screens = 18% of initial light * 18% = (0.18) * (0.18)

To get the final percentage, we multiply those two percentages:

Final transmission percentage = 0.18 * 0.18 = 0.0324 or 3.24%

Therefore, only 3.24% of the initial light is transmitted through two screens.

The function continues to increase through the second quadrant and out of the first quadrant.

Answers

Answer:

[tex]g(x)=1.5^{x}-4[/tex]

Step-by-step explanation:

Given:

The parent function is given as:

[tex]f(x)=1.5^{x}[/tex]

Let us consider a point on [tex]f(x)\ and\ g(x)[/tex] and compare their transformation.

The easiest point to consider is the y-intercept. At the y-intercept, the value of 'x' is 0.

The y-intercept of the function [tex]f(x)[/tex] is for [tex]x=0[/tex]. So,

[tex]f(0)=1.5^{0}=1[/tex]

The y-intercept of [tex]f(x)[/tex] is the point (0, 1).

Now, as per question, the transformed function [tex]g(x)[/tex] passes through the point (0, -3). Therefore,

The function [tex]g(x)[/tex] in the graph has the y-intercept equal to -3  as at y-intercept, the 'x' value is 0.

Therefore, the y-intercept of [tex]g(x)[/tex] is the point (0,-3).

Now, consider the transformation for the points (0, 1) and (0, -3).

[tex](0,1)\rightarrow (0,-3)[/tex]

Here, the 'x' value remains the same but the 'y' values decreases by 4 units. So, the rule will be:

[tex](x,y)\rightarrow (x,y-4)[/tex]

As per translation rules, if C units is added to 'y' value, then the graph moves up if 'C' is positive and moves down if 'C' is negative.

Also, the equation is of the form: [tex]g(x)=f(x)+C[/tex]

Here, [tex]C=-4[/tex].

Therefore, the graph shifts down by 4 units.

The equation of the function [tex]g(x)[/tex] is given as:

[tex]g(x)=f(x)+C=1.5^{x}-4[/tex]

Kay has 28 coins which includes nickels and dimes if the total is 2.35$, how many of each coin does Kay have?

Answers

Answer:

19 dimes and 9 nickels

Step-by-step explanation:

Model the situation using two equations, then solve the system.

let n be number of nickels and d be number of dimes.

n + d = 28     <= This equation is about the number of coins.

0.05n + 0.10d =  2.35   <=This equation is about the worth in dollars.

Rearrange n + d = 28.

n = 28 - d

Now we can substitute this equation into the other one.

Sub n =28-d at the "d" variable for the equation 0.05n + 0.10d =  2.35

0.05n + 0.10d =  2.35

Now there is only one variable.

0.05(28 - d) + 0.10d =  2.35   <=distribute this

0.05(28 - d) + 0.10d =  2.35

1.4 - 0.05d + 0.10d = 2.35   <=combine like terms

1.4 + 0.05d = 2.35    <= begin to isolate d

0.05d = 2.35 - 1.4

0.05d = 0.95

d = 0.95/0.05

d = 19

Now that we know d=19, we can substitute it into any equation.

Choose the equation n + d = 28 because the numbers are easier.

n + d = 28

n + 19 = 28    <=isolate n

n = 28 - 19

n = 9

Since n=9 and d=19, Kay has 9 nickels and 19 dimes.

The interior angles of a pentagon are x,x,2x, and 2x. What is the measure of the larger angles

Answers

Answer:

The measure of larger angle is 180°

Step-by-step explanation:

Given as :

For the pentagon

The measure of interior angles are

∠A = x ,

∠B = x ,

∠C = 2 x ,

∠D = 2 x ,

∠E = 3 x

We know, The sum of measure of all interior angles of pentagon = 540°

So, x + x + 2 x + 2 x + 3 x =   540°

or, 9 x =  540°

∴  x = [tex]\frac{540}{9}[/tex]

I.e x = 60°

So, The measure of angles are

∠A =  60°  ,

∠B =  60° ,

∠C = 2 ×  60° = 120° ,

∠D = 2 ×  60° = 120°,

A 30m high pole was standing at a point of the length side of a rectangle garden. If the angles of elevation of that pole form end points of that length are found 60 degree and 30 degree,find the length of that garden.​

Answers

Answer:

Length of the garden = 69.28 meters.

Step-by-step explanation:

See the attached diagram.

Let CD is the pole with a height of 30 m and the elevation of the top of the pole from the endpoints of the length A and B are 60° and 30° respectively.

So, ∠ DAC = 60° and ∠ DBC = 30°  

Now, Δ ACD is a right triangle and [tex]\tan 60 = \frac{CD}{AC}[/tex]

⇒ [tex]AC = \frac{CD}{\tan 60} = \frac{30}{\tan 60} = 17.32[/tex] meters.

Now, from Δ BCD which is a right triangle, [tex]\tan 30 = \frac{CD}{CB}[/tex]

⇒ [tex]CB = \frac{30}{\tan 30} = 51.96[/tex] meters.

Hence, AB = AC + CB = 17.32 + 51.96 = 69.28 meters. (Answer)

Answer:

The length of the rectangle garden is 20 [tex]\sqrt{3}[/tex] i.e 34.64 meters .

Step-by-step explanation:

Given as :

The height of the pole = H = 30 m

The two angles of elevation as 60° and 30°

Let The length of the rectangle garden = L m

Now, From figure

The measure from pole ground to first elevation 60° = x m

The measure from pole ground to second elevation 30° = (L + x ) m

Now, from triangle BOC

Tan Ф = [tex]\dfrac{\textrm perpendicular}{\textrm base}[/tex]

I.e Tan 60° = [tex]\dfrac{\textrm 30}{\textrm x}[/tex]

Or, [tex]\sqrt{3}[/tex] = [tex]\dfrac{\textrm 30}{\textrm x}[/tex]

or, x = [tex]\frac{30}{\sqrt{3} }[/tex]

I.e x = 10[tex]\sqrt{3}[/tex] meter      ...1

Again From triangle BAC

Tan Ф = [tex]\dfrac{\textrm perpendicular}{\textrm base}[/tex]

I.e Tan 30° = [tex]\dfrac{\textrm 30}{\textrm L + x}[/tex]

Or, [tex]\frac{1}{\sqrt{3} }[/tex] = [tex]\dfrac{\textrm 30}{\textrm L + x}[/tex]

Or, L + x = 30 × [tex]\sqrt{3}[/tex]   ....2

Put the value of x from  1 into 2

i.e L + 10[tex]\sqrt{3}[/tex] meter   = 30 × [tex]\sqrt{3}[/tex]

or, L = 30 [tex]\sqrt{3}[/tex] - 10 [tex]\sqrt{3}[/tex]  

Or, L = 20 [tex]\sqrt{3}[/tex] = 34.64 meters

I.e length of garden is 20 [tex]\sqrt{3}[/tex]

Hence The length of the rectangle garden is 20 [tex]\sqrt{3}[/tex] i.e 34.64 meters . answer

the value of y varies directly with x, and y= -3 when x=1. Find y when x=-6

Answers

Answer:

  y = 18

Step-by-step explanation:

Direct variation means y varies by the same factor x does. Here, x has changed by a factor of -6, so the new value of y is ...

  y = (-6)(-3) = 18

Final answer:

If y varies directly with x, and y = -3 when x = 1, the value of y when x = -6 is found using the formula y = kx. The value of y when x = -6 is 18.

Explanation:

In mathematics, if y varies directly with x, it means y = kx for some constant k. To find k, we substitute the given values of x and y into the equation, so -3 = k(1) gives k = -3.

Now that we have the value of k, we can find the value of y when x = -6. Substituting these values into our equation y = kx, we get y = -3*(-6), which simplifies to y = 18.

So when x = -6 and y varies directly with x, the value of y is 18.
