Question

Angles A and B are complements to each other,
If ∠A = (x-20°) and ∠B = (x-30°).Find the value of x.

Answer 1

Step-by-step explanation:

Two Angles are Complementary when they add up to 90 degrees.

so,  ∠A + ∠B = 90°

(x° - 20°) + (x° - 30°) = 90°

2x° - 50° = 90°

2x° = 90° + 50°

x = 140/2

x = 70°
