Question

Two supplementary are in the ratio 4:5. Find the angles​

Answer 1

Answer:

4x + 5x =180°

9x =180

x = 20

4×20 =80°

5×20=100°

Answer 2

$\huge\underbrace\mathbf\pink{Answer}$

Let two angles be 4x and 5x.

Sum of supplementary angles is 180 °

∴ 4x + 5x = 180 °

9x = 180°

${ \bf{\sf \: x = \frac{180}{9} }}$

So, one angle = 4x = 4×20 = 80 °

Another angle = 5x = 5×20 = 100 °

Larger Angle = 100°

Smaller Angle = 80°
