Question

two supplementary angles are in the ratio 5 is to 7 find the measures of the angles ?​

Answer 1

Answer:

5:7

5x+7x=180(by sum property of triangle)

12x= 180

x= 180/12

x= 15

Answer 2

Answer:

the sum of supplement ry angles=180°

let the ratio =5x,7x

5x+7x=180°

12x=180°

x=180/12

x=15

putting the value

5×15=75°

7×15=105°
