Question

two supplementery angles are in ratio7:5 find them​

Answer 1

Answer:

105,75

Step-by-step explanation:

let the supplementary angles be 7x and 5x.

so,7x+5x=180

12x=180

x=180/12

x=15

so,7x=7×15

=105

5x=5×15

=75

Answer 2

Given that the supplementary angles are in the ratio 7:5, therefore let hte angles be 7x and 5x

Given that,

7x+5x=180 [Both the angles are supplementary i.e. $90^{0}$]

12x = 180

x = 180/12

x = 15

Therefore the angles are

7x = 7*15 = 105

and 5x = 5*15 = 75
