first let the ratio be x=3x,4x,5x
then,we know sum of angle of tiangle =180°
then, 3x+4x+5x=180
12x=180
x=180/12
x=15
let,put the value of x
3×15=45°
4×15=60°
5×15=75°
then,we know sum of angle of tiangle =180°
then, 3x+4x+5x=180
12x=180
x=180/12
x=15
let,put the value of x
3×15=45°
4×15=60°
5×15=75°
