Question

Two supplementary angles are in ratio of 3 isto 7 ,find the angles

Answer 1

54° and 126°

Explanation:

let the angles be 3x and 7x respectively

Now,

3x+7x=180(supplementary angles)

10x=180

x=180/10=18

So, the angles are 3*18= 54°

And 7*18= 126°

Answer 2

Answer:

supplementary angle= 180°

3x+7x=180°

10x=180°

x=180°/10

x=18°

first angle=18*3=54°

second angle=18*7=126° Ans.
