Question

Two complementary angles are in the ratio of 2:4 .Find the angles

Answer 1

Let the 2 angles be 2x and 4x


A/Q --->
2x + 4x = 90 ........as the angles are complementary
6x = 90
x = 15°

The angles are -->
 2x = 2 x 15 = 30°
4x = 4 x 15 = 60°

∴ The angles are 30° and 60°

Answer 2

Let the two angles be 2p and 4p
As the angles are complementary sum of the angles is 90
2p+4p=90
6p=90
p=15
Therefore the angles are 30 and 60
