Question

9. The angles of a triangle are in the ratio 5:4: 3. Find the measure
of each angle.​

Answer 1

Answer:

let the angles of a trianle be 5x , 4x , 3x

now angle sum property of triangle

5x + 4x + 3x = 180

12x = 180

x = 180/12 = 15

now, 5x = 5 * 15 = 75

4x = 4 * 15 = 60

3x =3 * 15 = 45
