Question

the angle of a triangle are in the ratio 2 ratio 4 ratio 3 find the measure of greatest angle

Answer 1

Let angle be 2x,3x,4x
Sum=9x=180
X=20
Greater angle =80°

Answer 2

let the ratio constant be x
then we have three angle 2x,4x and 3x
as we know that sum of the angles of triangle is 180०
so,
2x+4x+3x=180
9x=180
x=20
greatest angle should be 4*20=80०
