Write a list of steps that are needed to find the measure of ∠B

Answer 1

Answer is interior angle B = 41

Using Exterior Angle Theorem, the exterior angle = the sum of two non-adjacent interior opposite angles. So

your formula

∠C = ∠A + ∠B

Fill in your known angles, using x for ∠B
113 = 72 + x

Subtract 72 from both sides to solve for x
113 - 72 = 72 - 72 + x

Simplify
41 = x
