Question

Ques - the angle of triangle are in the ratio of 2:3:4 find the measure of each angle of triangle

Answer 1

Let the angles of triangle be x

So angles r 2x 3x 4x

We know that
Sum of angles of triangle = 180

2x + 3x + 4x= 180
9x= 180

x= 20

So angles r 40 , 60 and 80 Ans

Answer 2

The sum  of three angles in triangle is 180 degree.

The three angle's ratio is 2:3:4

there 2x+3x+4x=180

9x=180

x=180/9=20

three angles, 2x,3x,4x. the small angle is 2x=2*20=40 degree
