Question

The angles are in the ratio 2:3:4

Answer 1

Let angles=2x,3x,4x
2x+3x+4x=180(Angle sum property)
9x=180
X=20
2x=2×20 =40
3x=3×20=60
4x=4×20=80

Answer 2

Let the common ratio be x.
So,
2x:3x:4x
Sum of all angles of a triangle = 180 degree
2x+3x+4x = 180 degree
9x = 180 degree
x = 180/9
x = 20 degree
So,
2(20) = 40 degree
3(20) = 60 degree
4(20) = 80 degree
