Question

Solve for x. THEN, find the measure of angle A. (Do not use the degree symbol. x + 61, x + 51, 80°

Answer 1

x + 61 + x + 51 = 80

2x + 112 = 80

Subtract 112 from both sides to isolate 2x:

2x = 80 - 112

2x = -32

x = -32 / 2

x = -16

A, Angle A = x + 61

Angle A = -16 + 61

Angle A = 45
