Question

Two supplementary angles are in the ratio 5:7. What is the value of the smaller angle?

Answer 1

Answer:

75

Step-by-step explanation:

consider each angle be 5x and 7x.then,

5x+7x=180

x=15

Answer 2

Answer:

Let the smaller angle be 5x

and larger angle be 7x

5x+7x=180°

12x=180°

x=180/12

x=15

Therefore,

The smaller angle is 5x =5×15=75°
