Question

find the measure of angle which is equal to its complement

Answer 1

let the angle be x 

(1) Complement of x = x 

✒ 90-x = x 

✒ 90 = x+x 

✒ 90 = 2x 

✒ 90/2 = x 

✒ 45° = x 

Answer 2

Hii There!!

Let the angle be 'x'

=) Complement angle will be 90°-x

=) Hence, according to the problem :-
= 90°-x=x
= 90°=2x
=. 45°=x

Therefore, x=45°


Hope it helps:)
