Question

Angles A and B are complements of each other
the measure
angle A x-20 and angle B = x-30.find the measure of both the angles?​

Answer 1

Answer:

Angle A = 50°

Angle B = 40°

Step-by-step explanation:

SOLUTION:-

Since, angle A and angle B are complementry angles therefore,there sum equals 90°

We have,

angle A + angle B = 90°

(x-20) + (x-30) = 90°

2x - 50 = 90°

2x = 140°

x = 70°

Therefore , angle A = x-20°

= 70-20

= 50°

angle B = x -30°

= 70-30

= 40°
