Question

find the angles of the triangle which are in the ratio 4is to3 is to 2

Answer 1

let the angle 4x 3x and2x
4x+3x+2x=180°
9x=180
x=20
the angles of triangle are 80°, 60°and40°

Answer 2

let the angles of triangle be 4x ,3x and 2x

4x +3x +2x=180 (A S P of triangle)
=> 9x=180
=> x=180/9
x= 20
therefore the angles of triangle are :
4×20 ,3×20 ,2×20
80 ,60 , 40
