15. Two complementary angles differ by 20°. Find the measure of each angle.

Answer»

Sum of two complementary angles= 90°let one of the complementary angles be x and second angle be x-20then a/q x+ x-20=90 =2x = 90+20 = x= 110/2 ∴x= 55so measure of one angle is 55°andthe second angle is 55-20= 35°and 55+35= 90°
