Question

. A and B are vertical angles. If mA = (5x – 28) and

mB = (3x + 4)º, find the measure of each angle.

Answer 1

Both are 56°

Explanation:

5x-28=3x+4

x=16

5(16)-28= 56°

Answer 2

measure of both angles is 52°

x = 16

Explanation:

5x - 28 = 3x + 4

2x - 28 = 4

2x = 32

x = 16

Plug in 16 for 'x': 3(16) + 4 = 48 + 4 = 52°
