Answer: The angles are 80 and 100.

Step-by-step explanation:

Total angles for a supplementary angle is 180°.

Since the angles are in 5:4

5/9 × 180= 100

4/9 × 180= 80

The angles are 100° and 80°.

Step-by-step explanation:

Given,

Two supplementary angles are in ratio 5:4

To find the value of each angle.

Let,

Two angles are 5x and 4x.

For supplementary angle sum of two angles is 180°

So,

5x+4x = 180°

or, 9x= 180°

or, x = 180÷9

or, x = 20°

The angles are 100° and 80°.
