Question

In in triangle, the ratio of angles is 3:7:5 find the measure of all this
angles ?​

Answer 1

Answer:

let the 3 angles be 3x, 7x and 5x

sum of all angles in a triangle = 180

3x + 7x + 5x = 180

15x = 180

x = 180/15

x = 12

3x = 3(12) = 36

7x = 7(12) = 84

5x = 5(12) = 60

The angles are 36, 84 and 60
