Q1 of 23 Page 87

Find the complement of each of the following angles.

i. 63° ii. 24°


iii. 48° iv. 35°


v. 20°

i. We know that two angles are said to be complementary if their sum is 90°.


So, the complement of 63° = 90° - 63° = 27°


ii. We know that two angles are said to be complementary if their sum is 90°.


So, the complement of 24° = 90° - 24° = 66°


iii. We know that two angles are said to be complementary if their sum is 90°.


So, the complement of 48° = 90° - 48° = 42°


iv. We know that two angles are said to be complementary if their sum is 90°.


So, the complement of 35° = 90° - 35° = 55°


v. We know that two angles are said to be complementary if their sum is 90°.


So, the complement of 20° = 90° - 20° = 70°
