Question

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

Answer 1

Angle B = 41

Explanation:

Step 1: Finding inner C.

A line is 180, so line ACD will be 180.

If one side 113, knowing that line is 180, other part of the line is 180-113 = 67.

Step 2: Finding B.

All angles in a triangle add up to 180.

Given A = 72

We solved for C in step 1, C = 67

A + B + C = 180

72 + B + 67 = 180

B + 139 = 180

B = 180 - 139

B = 41
