What is the approximate length of arc s on the circle below? use 3.14 for pi. round your answer to the nearest tenth.

we know that

To find the length of arc S on the circle, use proportion

in this problem we have

substitute

Round to the nearest tenth

therefore

the answer is

x = -4

step-by-step explanation:

- 20 - 4(x + 3) = 4x

=> -20 - 4x - 12 = 4x

=> - 32 -4x = 4x

=> -32 = 4x + 4x

=> - 32 = 8x

=> -32/8 = x

=> -4 = x
