Find the complement of each of the following angles:

Solution:

The sum of complementary angles is always 90°. If the given angle is x, then we can find complementary angle by subtracting x from 90°. 

(i) Given angle = 20°

Complement angle of 20° = 90° − given angle

90° − 20° = 70°

(ii) Given angle = 63°

Complement angle of 63° = 90° − given angle

90° − 63° = 27°

(iii) Given angle = 57°

Complement angle of 57° = 90° − given angle

90° − 57° = 33°
