Question

if the ratio of angle of a triangle is 2 : 3 : 4,find the measure of each angle.

Answer 1

2x+3x+4x= 180
9x=180
x=20°
therefore,
2x=2×20=40°
3x=3×20=60°
4x=4×20=80°

Answer 2

let the ratio be x
2x + 3x + 4 x is equal to 180
9 x is equal to 180 degree
x is equal to 20 degree
so. the angles are 40° ,60 and 80 degree
