Answer:

151

Explanation:

So you have to start by finding the total number of degrees inside the shape. The shape has 5 sides.

So using this formula:

(n-2) * 180

(5-2) * 180

= 540 degrees inside the shape

Then solve for x.

5x +2 + 10x - 3 + 8x -19 + 13x - 31 + 7x -11 = 540

43x -62 = 540

43x = 602

x = 14

Plug in for S.

13 (14) -31
