If the angles of the triangle are in ratio of 2:3:4 then let us take the proportionality constant to be x.
2x+3x+4x=180 degree (angle sum property)
9x=180
x=180/9=20
Therefore 2x=40 3x=60 4x=80.
2x+3x+4x=180 degree (angle sum property)
9x=180
x=180/9=20
Therefore 2x=40 3x=60 4x=80.

firstly sum up the ratio=2+3+4=9
then =ratio 2=2/9*180=180= 40
ratio 3 =3/9*180=60
ratio 4 =4/9*180=80
then =ratio 2=2/9*180=180= 40
ratio 3 =3/9*180=60
ratio 4 =4/9*180=80
