Question

The three angles of a triangle have a ratio of 5:7:13. Find the measure of each angle.

Answer 1

let ratio be 5x,7x and 13x

we have

5x+7x+13x=180 sum of interior angle of the triangle is 180°

25x=180

x=180/25=36/5

Explanation:

missing Angle are

5x=5×36/5=36°

7x=7×36/5=50.4°

13x=13×36/5=93.6°
