Question

3. A and B are complementary angles. If angle A = x + 20° and Angle B=x-10°, find angle A and angle B.​

Answer 1

Answer:

Angle A = 60°

Angle B = 30°

Step-by-step explanation:

Angle A = x + 20°

Angle B = x - 10°

complementary angle = Angle A + Angle B = 90°

= x + 20° + x - 10° = 90°

= 2x + 10° = 90°

= 2x = 90° - 10°

= 2x = 80°

= x = 80°/2 = 40°

Now,

Angle A = x + 20° = 40° + 20° = 60°

Angle B = x - 10° = 40° - 10° = 30°
