Question

angle of a tringle are in the ratio 2:4:3. the smallest angle of the triangle is_

Answer 1

2x+4x+3x=180
9x=180
x=180/9
x=20

2x=40degree
4x=80degree
3x=60degree

smallest angle is of  40degree

Answer 2

let all the angles of the triangle be 2x 4x and 3x.
2x+4x+3x=180 degree
9x=180 degree
x=180÷9=20 degree
2x= 2×20=40 degree
4x=4×20=80 degree
3x=3×20=60 degree


SO smallest side is 2x.
