Question

Two supplementary angles are in the ratio 5 : 7 . Find the measure of the angles.

​

Answer 1

Answer:

Let the ratios be 5x and 7x

Sum of 2 supplementary angles=180

5x+7x=180

12x=180

x=180/12=15

therefore tha angles are

5x=5×15=75

7x=7×15=105

hope this helps you

Answer 2

Answer:

the supplementary angles are

75:105
