Question

two supplementary angle are in the ratio 4:5 find the angle​

Answer 1

Given

two supplementary angle are in the ratio 4:5

To find

Find the angles

Solution

As we know that supplementary means the sum of two angles is equal to 180°

According to the question

Let the angle be 4x and 5x

=> 4x + 5x = 180

=> 9x = 180

=> x = 180/9

=> x = 20°

Hence, required angles

4x = 4 × 20 = 80°

4x = 4 × 20 = 80°5x = 5 × 20 = 100°
