Question

What is the value of x?

Answer 1

the sum of the interior angles equal 720

112 + 133 +128 +100 + 120 = 593

720 - 593 = 127

x = 127 degrees

Answer 2

(n - 2 ) 180 = sum of interior angles

n = 6, because it is the number of angles the polygon has

(6-2) 180 = 720

720 - 120 - 100 - 128 - 133 - 112 = x

x = 127


hope this helps
