Question

Two angles are complementary and one angle is 18° more than tne other, then find angles.

Answer 1

Let smaller angle be x° bigger angle be y° 

Since these two angles are complementary

x + y = 90° ………… (1) 

Since bigger angle is more than smaller angle by 18°, 

y – x = 18° ………….(2) 

By solving (1) & (2), we get 

x = 36°, y = 54°
