Answer 1

Answer:

4x+5x=180°

9x=180°

x=20°

4x=80°,5x=100°

Answer 2

$\underline{\bigstar{\sf\ Given:-}}$

• Ratio of two supplementry of an angles is 4:5.

$\underline{\bigstar{\sf\ To\:Find:-}}$

• Both angles.

$\underline{\bigstar{\sf\ Solution:-}}$

Let the angles be 4x and 5x.

A.T.Q

4x + 5x = 180°

9x = 180°

x = 180/9

x = 20°

First angle = 4 × 20 = 80°

Second angle = 5 × 20 = 100°
