Question

The angle of a triangle are in ratio 1:2:3 . Find the angles in radians.

Answer 1

let the first angle be 1x
second angle be 2x
third angle be 3x

sum of all the angles of a triangle is 180°
1x+2x+3x=180°
6x=180°
x=180÷6
x=30°

hence,
first angle=1x=30°
second angle=2x=60°
third angle=3x=90°
