Describe the type of angles formed when you divide a circle into 4 equal parts

Answers

we know that

when a circle is divided into four equal parts, we will get 4 right angles
so
360°/4=90° each part

see the attached figure to better understand the problem

When we divide a circle into 4 equal parts, the angles formed are the right angles.

When a circle is divided into 4 equal parts, we get 4 quarters of the circle.

What is a quarter of a circle?

The area that is intercepted by two radii that are at 90° to each other and a quarter portion of the circumference of a circle is known as a quarter circle.

In a quarter of a circle, the angle between radii is 90 degrees.

So, When we divide a circle into 4 equal parts, the angles formed are the right angles.

Hence, When we divide a circle into 4 equal parts, the angles formed are the right angles.

Anna is in a phone booth with $1.35 in change. a call home costs 60 cents for the first five minutes and 15 cents for each additional minute. How long can she talk?

Answers

for 10 minutes, if she has 5 minutes to talk we would subtract 60 cents from 1.35 leaving us with 75 cents, so that could be split up into 15 cents 5 times making it 5 more minutes. so she can talk for 10 minutes

What is the total number of outcomes in the sample space for Tossing a coin and spinning a spinner with 5 equal sections

Answers

2/5 i believe
because a coin has two sides ( heads or tails) then the spinner is 5 equal sections so 2/5 <3
hope it helps

There are 10 possible outcomes in the sample space when tossing a coin and spinning a spinner with 5 equal sections.

When tossing a coin and spinning a spinner with 5 equal sections, the total number of outcomes in the sample space can be calculated by multiplying the number of outcomes for each event.

For the coin toss, there are 2 possible outcomes: heads (H) or tails (T).

For spinning the spinner, there are 5 possible outcomes: each of the 5 sections.

So, the total number of outcomes in the sample space is the product of these two numbers:2×5=10.

solve for x please!!!!

Answers

11) Since the triangle has a pair of congruent base angles, it is an isosceles triangle which means that the two pairs of legs are congruent.

Make them equal to each other in an equation.

5x = x + 20

Subtract x from both sides.

4x = 20

Divide both sides by 4.

x = 5

12) The two legs are congruent so that means the base angles must be congruent. First find the measure of the base angles. Create an equation:

x + x + 50 = 180

Combine like terms.

2x + 50 = 180

Subtract 50 from both sides.

2x = 130

Divide both sides by 2.

x = 65

Now make the base angle plus x equal 180, because they form a straight line.

65 + x = 180

Subtract 65 from both sides.

x = 115

13) You know the vertex angle (top angle) is 90 degrees because it is supplementary to a right angle. The triangle is isosceles because the two legs are congruent, so make the base angles plus 90 add up to 180 in an equation.

x + x + 90 = 180

Combine like terms.

2x + 90 = 180

Subtract 90 from both sides.

2x = 90

Divide both sides by 2.

x = 45

a new parking lot is being built for a medical office. the expression representing the number of parking spots in the new lot is 15x/4-9 where x represents the number of parking lots in the first row. how many spots are in the parking lot if there are 32 parking spots in the first row?

Answers

111 parking spots. 15x32 = 480 480 divided by 4 is 120 and 120 - 9 = 111

Answer:

The number of spots in the parking lot if there are 32 parking spots in the first row =111.

Step-by-step explanation:

We are given that a new parking lot is being built for a medical office.

We are given that

The expression representing the number of parking spots in the new lot =[tex]\frac{15x}{4}-9[/tex]

Where x= The number of parking lots in the first row

We have to find number of spots in the parking lot when parking spots in the first row is 32.

The number of parking spots in the first row =x=32

Substitute the value of x in the given expression then we get

Number of spots in the parking lot =[tex]\frac{15\times 32}{4}-9[/tex]

Number of spots in the parking lot=[tex]\frac{480}{4}-9[/tex]

The number of spots in the parking lot=120-9

The number of spots in the parking lot=111.

Hence, the number of spots in the parking lot if there are 32 parking spots in the first row=111.

Find the area of the triangle. (round to the nearest whole number)

Answers

Answer: 210 square inches

============================================================

Explanation:

Check out the attached image. I've added in points A through D. The points A,B,C are the vertices of the largest triangle. Point D is directly below point A, and point D is on segment BC.

To find the area of the largest triangle ABC, we need the base length BC, which is broken up into segments x and y

x = length from C to D
y = length from D to B

Let's find x first

Triangle ADC is a right triangle, so we can use the pythagorean theorem
a^2 + b^2 = c^2
x^2 + 15^2 = 17^2
x^2 + 225 = 289
x^2 = 289 - 225
x^2 = 64
x = sqrt(64)
x = 8

Follow similar steps to find y
a^2 + b^2 = c^2
y^2 + 15^2 = 25^2
y^2 + 225 = 625
y^2 = 625 - 225
y^2 = 400
y = sqrt(400)
y = 20

Therefore
BC = x+y
BC = 8+20
BC = 28

The base of the triangle ABC is BC = 28 units
b = base
b = 28

The height is AD = 15
h = height
h = 15

We can now find the area of triangle ABC
Area = b*h/2
Area = 28*15/2
Area = 420/2
Area = 210

The area of the triangle is 210 square inches

find the value of sin2a, if tana=-12/5 in the fourth quadrant

Answers

[tex]\tan a=-\dfrac{12}5[/tex]

Recall the following identities:

[tex]1+\tan^2a=\sec^2a=\dfrac1{\cos^2a}[/tex]
[tex]\cos^2a=\dfrac{1+\cos2a}a[/tex]

from which we get

[tex]1+\left(-\dfrac{12}5\right)^2=\dfrac1{\cos^2a}[/tex]
[tex]\implies\cos^2a=\dfrac{25}{169}[/tex]

Since [tex]a[/tex] is in the fourth quadrant [tex]\left(\dfrac{3\pi}2<a<2\pi\right)[/tex] we know that [tex]\cos a[/tex] should be positive, so when we take the square root here, we should take the positive root.

[tex]\implies\cos a=\sqrt{\dfrac{25}{169}}=\dfrac5{13}[/tex]

Now recall that

[tex]\cos^2a+\sin^2a=1[/tex]

and since [tex]a[/tex] is in the fourth quadrant, we expect [tex]\sin a[/tex] to be negative. So,

[tex]\sin^2a=1-\cos^2a=\dfrac{144}{169}\implies\sin a=-\sqrt{\dfrac{144}{169}}=-\dfrac{12}{13}[/tex]

One final identity:

[tex]\sin2a=2\sin a\cos a[/tex]

from which we get

[tex]\sin2a=2\cdot\left(-\dfrac{12}{13}\right)\cdot\dfrac5{13}=-\dfrac{120}{169}[/tex]
