Question

Two angles are a linear pair. Their measures are represented by x+10 and 3x+10. What are the measures of the angles

Answer 1

50° and 130°

Explanation:

Linear pair of angles are supplementary, which means their sum is 180

x + 10 + 3x + 10 = 180

4x + 20 = 180

4x = 160

x = 40

x + 10 = 40 + 10 = 50°

3x + 10 = 3(40) + 10 = 120 + 10 = 130°
