Let angles of the triangle=5x,4x,3x
5x+4x+3x=180(Angle Sum Property)
12x=180
x=180/12
x=15
5x=5×15=75
4x=4×15=60
3x=3×15=45
The angles of the triangle are 75°,60°,45°.

5x+4x+3x=180°
12x=180
x=180/12
x= 15
so 5x= 5×15 =75
4x=4×15=60
3x=3×15= 45
so, 75+60+45= 180
12x=180
x=180/12
x= 15
so 5x= 5×15 =75
4x=4×15=60
3x=3×15= 45
so, 75+60+45= 180
