Pentagon has 5 sides

The formula for finding the sum of the measure of the interior angles is (n - 2) * 180

(5-2)×180= 3×180=540

To get each interior angles

540/5 = 108

180 -108 = 72

To get x

72+72+x= 180 (sum if angles in a triangle)

144+x= 180

x = 180 -144 = 36

2. x is part of the interior angles = 108
