Question

Angle A and angle B are complementary. Find angle A and angle B.

angleA = (3x + 46)°
angleB = (x − 4)°

Answer 1

Angle A is 82

Angle B is 8

Explanation:

Complementary means they add to 90 degrees

3x+46+x-4=90

4x+42=90

4x=48

x=12

Angle A is 3(12)+46= 82

Angle B is 12-4=8

82+8=90
