Question

First identify the angle RELATIONSHIP, then find the measure of the angle indicated in bold.

Answer 1

Same-side interior angles

m∠ = 110°

Explanation:

Step 1: Set up equation

6x + 16 + 13x - 7 = 180

Step 2: Combine like terms

19x + 9 = 180

Step 3: Isolate x and solve

19x = 171

x = 9

13(9) - 7 = 110°
