Is it

A 180

B 120

C 45

D 60

Answers

Answer:

60° .

....................

The answer is 60.

Since angle 1 and angle three are on the same line they have to have complimentary angles. So, 180 (degrees of a straight line) minus the angle 1 would give:

180 - 120 = 60.

An unknown number y is 15 more than an unknown number x. The number y is also x less than 8. The equations to find x and y are shown below. y = x + 15
y = −x + 8

Which of the following statements is a correct step to find x and y?
Answers:
Multiply the equations to eliminate y.

Add the equations to eliminate x.

Write the points where the graphs of the equations intersect the x-axis.

Write the points where the graphs of the equations intersect the y-axis.

Answers

Add the equations to eliminate x.

y = x + 15
y = −x + 8

2y = 23

y = 11.5

All right, if I remember correctly... You have to add the equations to eliminate x.

Now, how you do that... let me search my memory for that xDDDD

A circle has a radius of 8 inches. Find the area of a sector of the circle if the sector has an arc that measures 45°.2 sq. in.?
8 sq. in.?
16 sq. in.?

Answers

The formula of the sector is expressed in the following expression:
Area = 0.5 * r^2 * theta
where r is the radius of the circle and theta is the angle in which the sector is measured and is expressed in radians. In this case, upon substitution
Area = 0.5*8^2 * 45 degrees * (pi/180 degrees)Area = 25.15 square inches

Answer:

The area of the sector is 8π or 25.133 square inches.

Step-by-step explanation:

The formula for area of a section is

$A=\pi r^2* ((\theta)/(360))$
