Question

the angles of a triangle are in the ratio 2 : 3 :4. find the angles.

Answer 1

Let angle be x
2x +3x+4x =180
9x=180
X=180/9
=20
2×20=40

3×20=60

4×20=80

Answer 2

Let the angles be 2x 3x and 4x respectively
Sum of all the angles of triangle =180*
Therefore
2x+3x+4x=180
9x=180
X=180/9
X=20
2x=2*20=40*
3x=3*20=60*
4x=4*20=80*
So the angles are 40*,60*,80* respectively
