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

Answer:

∠A = 50° and ∠B = 40°

Step-by-step explanation:

∠A + ∠B = 90°

(x-20°) + (x-30°) = 90°

2x-50°=90°

2x=90°+50°

x=140°/2

x=70°

Therefore, ∠A = (x-20°) = 70°-20°=50°

and ∠B = (x-30°) = 70°-30°=40°

I Hope it's clear
