Question

find the measure of angle of a triangle in each case of the following
the angles are in the ratio2:3:4

Answer 1

2x + 3x + 4x = 180
9x = 180
x = 180/9
x = 20
1st side is 40
2nd side is 60
3rd side is 80

Answer 2

sum of triangle = 180
let ratio be x.
therefore
ratio= 2x,3x,4x

A.T.Q

2x+3x+4x=180
9x=180
x=180/9=20

2x= 2×20=40
3x=3×20=60
4x =4×20=80
