Question

The angles of a ∆ ABC are in the ratio 2:3:4 . Find the largest angle of the triangle. and explain also.

Answer 1

let the angles of the triangle be 2x,3x and 4x.
we know ,
sum of 3 angles of a triangle is 180°
A.T.Q,
2x+3x+4x=180
=>9x=180
=>x=20
Therefore,
2x=40°
3x=60°
4x=80°
Hope it helps..:)

Answer 2

sum : 9
1St angle = 2/9*180
=40

2nd angle = 3/ 9*180
= 60
3rd angle = 4/9*180
=80
