Hey ananya
your answer is here
let angles of triangle is 2k,3k nd 4k
then 2k+3k+4k = 180°
k = 20
thus, angle of triangle are 40°,60° nd 80°

so largest angle is 80°
Thanks

According to the sum of angle of a triangle....

Let the ratio be 2x, 3x,4x.
Now, 2x+3x+4x=180
9x=180
x=180/9
x=20
So, 2x= 2*20=40
3x=3*20=60
4x=4*20=80
Hence, the largest angle is 4x.
