Answer:
ans:x=70
Step-by-step explanation:
as it is mentioned that they are Complementary :
x-20+x-30=90
2x-50=90
2x= 140[90+50]

Step-by-step explanation:
Since, ∠A & ∠B are complementary.
so, ∠A + ∠B = 90°
⇒(x-20°)+(x-30°) = 90°
⇒2x-50° = 90°
⇒2x = 90°+50° = 140°
⇒x =
⇒x = 70°
so, ∠A = 70°-20° = 50°
∠B = 70°-30° = 40°
