Question

If two supplementary are in the ratio 4:5 then the angles ar​

Answer 1

Step-by-step explanation:

4x + 5x = 180°

=> 9x = 180°

=> x = 20

therefore angles are,

4x = 4×20 = 80°

5x = 5 × 20 = 100°

Answer 2

the angles are in ratio 4x:5x

4x+5x=180

9x=180

x=20°

Therefore the angles are 80°,100°
