Find the Complement of each of the following angles.
(a) 20° (b) 63°

Academic Mathematics NCERT Class 7

Given :

The given angles are (a) 20° and (b) 63°

To find :

We have to find the complement of given angles.

Solution :

An angle is said to be the complement of another angle if their sum is $90 °.$

If x is an angle, then its complement is $90 ° - x.$

(a) 20°

Complement of $20 ° = 90 ° - 20 ° = 70 °.$

$Complement of 20° is 70°$

(b) 63°

Complement of $63 ° = 90 ° - 63 ° = 27 °.$

$Complement of 63° is 27°$
