Question

Find the complementary angle of 89,83,18,90.

Answer 1

Step-by-step explanation:

complementary refer to the 90 degree

now we are going to find what are the angles that hasto be added it make it complementary

now

1) 89° = 90°-89° = 1°

therefore, 1° is the complementary angle of 89°

2) 83° = 90°- 83° = 7°

therefore, 7° is the complementary angle of 83°

3) 18° = 90°-18° = 72°

therefore, 72° is the complementary angle of 18°

4) 90° = 90°-90° = 0°

therefore the given angle is already complementary

Answer 2

Complementary of 89 = 90° - 89°

= 1°

Complementary of 83 = 90° - 83°

= 7°

Complementary of 18 = 90° - 18°

= 72°

Complementary of 90 = 90° - 90°

= 0°
