Question

52°

Two adjacent angles are on a straight line. One angle has a measure of (5x - 28) ° and the other angle has a
measure of (8x) °. What is the measure of the second angle? (1 point)

O

○ 120°

○ 128°

16°

Answer 1

Let the angles be supplementary: (5x − 28) + 8x = 180.
So 13x − 28 = 180 → 13x = 208 → x = 16.
The second angle = 8x = 8(16) = 128°.
