Question

If two supplemenyary angle are in the ratio 4:5then find the angles

Answer 1

Answer:

4x+5x=180

9x=180

x=180/9

x=20

4*20=80

5*20=100

the angles t 80 and 100

Answer 2

Explanation:

let the common ratio= x

therefore. 5x. 4x.

we know that sum of supplementary angle is 180

A/Q

5x + 4x. = 180°

9x. = 180°

x. = 180 / 9

x. = 20.

therefore. 5x = 5 * 20 =100

4x. = 4* 20. =80

since. first angle = 100

second angle= 80
