A four sided figure that figs inside a circle is called a cyclic quadrilateral. One of the properties of such a figure is that the opposite angles add up to 180o

2x + 3 + 4x + 3 = 180o
6x + 6 = 180
6x = 174
x = 174 / 6
x = 29

C = 2x + 1
C = 2*29 + 1
C = 59o
Answer 2

2x+3+4x+3= 180o     6x+6=180    6x=174    174/6   29

2x+1    (2)29+1     59o

Select the following series as arithmetic, geometric, or neither. 1 + 2 + 3 + 4 + . . . + 10

Answers

The series is an arithmetic series.

The progression has a common difference of 1. You can tell because it involves a plus sign, which is indicative of an arithmetic progression,

A geometric progression would include multiplying the numbers by a certain amount. For example:
1, 3, 9, 27 ... 243
In this series, you multiply the numbers by three to get your answer.

The following series is an arithmetic series. Because the progressive term has a difference of 1.

What is a sequence?

It is defined as the systematic way of representing the data that follows a certain rule of arithmetic.

The given equation is;

1 + 2 + 3 + 4 + . . . + 10

The series is arithmetic in nature. The typical difference in the progression is 1. Because it has a plus sign, which indicates an arithmetic progression.

Hence, the following series is an arithmetic series.

Answers

Part A)In a 45-45-90 triangle, what is the length of the hypotenuse when the length of one of the legs is 11 in.?

we know that
cos 45°=√2/2
[he length of the hypotenuse]=11/cos 45-----------> 11/(√2/2)----> (11*2)/√2
=22/√2-------> 11√2 in

the answer Part A) is 11√2 in

Part B) What is the exact value of sin 45° ?

we know that
sin 45°=11/(11√2)-------> 1/√2---------> (1/√2)*(√2/√2)-----> √2/2
the answer part b) is √2/2

Part C)
What is the area of a regular hexagon with a side length of 4 m?

we know that

In case of a regular hexagon  each of the six triangles that are formed by connecting its center with all six vertices is an equilateral triangle with a side equaled to 4 m.
The area of this hexagon is six times greater than the area of such a triangle

In an equilateral triangle with a side d 
the altitude h can be calculate from the Pythagorean Theorem as
h²=d²−(d/2)²=(3/4)d²
Therefore, 
h=d√3/2

Area of such a triangle is
A=d*h/2------------> d²*√3/4
From this the area of the regular hexagon with a side d is
S=6*A----------> d²3√3/2
for d=4 m
S=4²3√3/2------> 24√3 m²------------> 41.57 m²

the answer Part C) is 41.57 m²

Part D) In a 30-60-90 triangle, what is the length of the hypotenuse when the shorter leg is 5 cm?
[he length of the hypotenuse]=5/sin 30--------> 5/(1/2)---------> 10 cm

the answer part D) is 10 cm

If we take the amount of points to be x before doing any operations on it ,
george has 2 times points of x 
however x is 4 points less than sisters points which is 16 points 
Then we subtract 4 from 16 = 12
12 is equal to x and george has twice of x 
Therefore we first subtract 4 from 16 and then multiply  it by 2, thats 12*2 = 24 
therefore george has 24 points 
the operations are subtraction and multiplication in order

Answers

A. First notice that the function is moved up by two units from the origin, not four, so the answer must be in A, B, and D. Also notice that the period of the function is pi instead of 2pi, so the coefficient before x is 2pi/pi=2, so eliminate B. The function is opposite of original sin function, so there's a negative sign in front of the expression. The answer is A.

Gretchen's gross annual salary is $57,852 what is the maximum amount of rent she can afford to pay

Answers

Answer: Varies depending on the percent that you use.

To find the amount that you should spend on rent, you simply multiply your total annual salary by the recommend percent. Use the one that you were given.

A common percent is 30%.

So you would do the following problem if you were using 30%.
0.30 x 57852 = $17,355.6.


Rent should be no more than 28% of a person's gross monthly income. Divide the annual salary by 12 and multiply the quotient by 0.28.

Yulia estimates college tuition and fees, room and board, books, and other charges total $15,350. She will receive a $1500 scholarship. If she has 4 years to save, how much should Yulia save per month to cover the costs of college (minus the scholarship)? A. $288.54 B. $319.79 C. $3462.50 D. $3837.50

Answers

We know the the total cost of Yulia's college education is $15,350. We also know that she will receive a $1500 scholarship, so she will have to pay [tex]15350-1500=13850[/tex]$. A year has 12 months, so 4 years have [tex]4(12)=48[/tex] months.
Now to find how much she will need to save each month, we are going to divide the total cost of her college education by 48 months:
[tex] \frac{13850}{48} =288.54[/tex]

We can conclude that Yulia will have to save $288.54 per month to cover the costs of her college education. Therefore, the correct answer is: A. $288.54

Static electricity illustrates or mostly related to the Law of Conservation of Charge.

For the rational equation, x^2+5x+6/x+3=1 , what is a valid value of x?.

Answers

the correct answer is -1.

Answer:

B. -1

Step-by-step explanation:

We have the equation, [tex]\frac{x^{2}+5x+6}{x+3}=1[/tex].

Now, factorizing the polynomial [tex]x^{2}+5x+6[/tex], we get that the factors of the polynomial are (x+3) and (x+2).

So, we get,

[tex]\frac{x^{2}+5x+6}{x+3}=1[/tex]

i.e. [tex]\frac{(x+3)(x+2)}{x+3}=1[/tex]

i.e. x + 2 = 1

i.e. x = -1.

Hence, we get that the value of x is -1.

JL is a diameter of circle K. if tangents to circle K are construvted through points L and J, what relationship would exist between the two tangents? explian

Answers

check the picture below.

notice, the left-hand-side of the picture is the tangents segment theorem, both tangents are the same length and the point of tangency, in red, is always a right-angle, however note that they're touching a radius segment, not a diameter one, and the radii lines are slanted some.

notice the right-hand-side of the picture, the points of tangency at J and L are right-angles, and the two tangents at those points, will simply be parallel, and never touch each other.

What is the value of z in the equation 11 + z = 6?

Answers

-5 will be your answer. Hope this helps!

Answer:

z = -5

Step-by-step explanation:

To find the value of z in the equation 11 + z = 6

we will simply subtract 11 from both-side of the equation. That is;

11 + z = 6

Subtract 11 from both-side of the equation

11 - 11 + z  = 6 - 11

(On the left-hand side of the equation 11 will be subtracted from 11 which gives zero, thereby leaving us with just z while on the right-hand side of the equation 11 will be subtracted from 6 which will give negative 5)

z = -5

Match each angle measure in degrees with its equivalent measure in radians

Answers

To convert angle from radian measure to degree measure, multiply it by 180/π.

So,
a) 5π/4 in degree measure will be:

[tex] \frac{5 \pi }{4}* \frac{180}{ \pi } = 225[/tex]

So, 5π/4 radian is equal to 225°.

b) 9π/5 in degree measure will be:

[tex] \frac{9 \pi }{5}* \frac{180}{ \pi } = 324 [/tex]

So, 9π/5 radian is equal to 324°.

c) 2π/3 in degree measure will be:

[tex] \frac{2 \pi }{3}* \frac{180}{ \pi } = 120[/tex]

So, 2π/3 radian is equal to 120°.

d) 4π/9 in degree measure will be:

[tex] \frac{4 \pi }{9}* \frac{180}{ \pi } = 80[/tex]

So, 4π/9 radian is equal to 80°.

e) 5π/6 in degree measure will be:

[tex] \frac{5 \pi }{6}* \frac{180}{ \pi } = 150[/tex]

So, 5π/6 radian is equal to 150°.

f) 7π/4 in degree measure will be:

[tex] \frac{7 \pi }{4}* \frac{180}{ \pi } = 315[/tex]

So, 7π/4 radian is equal to 315°.

Hello! 1,000 points are needed to go to a water park, and 424 points are already added, with 9 more games. An equation that would help find the average number of points is 9x + 424 = 1,000.

How to solve it:

Okay. So first off, lets subtract 424 from both sides. 424 - 424 cancels out. 1,000 - 424 is 576. That makes 9x = 576. Now, divide each side by 9 to isolate the c. 9x/9 cancels out. 576/9 is 64. There. x = 64. The team will need to score an average of 64 points in their remaining games in order to reach their goal.
