Question

(y-20) degree and (y+30) degree are the measures of complementary angles . Find the measures of each angle .

Answer 1

Sum of two complementary angles= 90°

let one of the complementary angles be y-20 and the second angle be y+20
then a/q y-20+y+20=90
=2y = 90
= Y= 90/2

∴x= 45
so measure of one angle is 45°
and the
second angle is 45-20= 25°

And other ,: 45+30=75°
