1) d. All of the above are true

2) b. 21.8°

3) 7x + 10 = 150 ; x = 20°

4) b. The measure of angle B is 117°

Step-by-step explanation:

1) 4x + 8x = 180

12x = 180

x = 15°

4x = 60°

8x = 120°

2) x = 90 - 68.2

x = 21.8°

3) 7x + 10 = 150

(Vertically opposite angles)

7x = 140

x = 20°

4) Angle A = 180 - 90 - 27

Angle A = 63°

Angle B = 180 - 63

Angle B = 117°

Angle C = 180 - 117

Angle C = 63°

the figures below are made out of circles, semicircles, quarter … find the area and the perimeter of each figure and give your answers as a completely simplified exact value in terms of π (no approximations). remember that we'll also have to cut whatever areas we get in half, since we're only dealing im pretty sure that is the right answer
