The angles are 72° and 18°

Step-by-step explanation:

Given :- the sum of two angles is complementary

To find :- value of two angles

Solutions :- Let the complementary angles be x

so, the second angle be 4x

according to the question

x+4x = 90°

5x = 90°

x = 90°/5

x = 18°

so, the measure of complementary angle is 180°

and the measure of second angle = 4 x

= 4 × 18°

= 72°

hence the angles are 72° and 18°
