Question

Two supplementary angles are in the ratio of 4:5 find the angle

Answer 1

Answer:

Two angles measure 80° and 100°.

Step-by-step explanation:

We know that, supplementary angles are two angles whose sum add up to 180°.

So, let the common ratio be x.

Therefore,

Sum of given two angles is

4x + 5x = 180°

9x = 180°

x = 180/9 = 20°

Thus, the two angles are

4x = 4(20°) = 80°

5x = 5(20°) = 100°

Answer 2

Answer:

when the sum of the two angles is 180°then they are called supplementary angles.

let the angles are 4x and 5x

so,

4x+5x=180

=> 9x=180

=> x=180/9

=> x=20

so the angles are 4.20°=80° and 5.20°=100°
