Angles are 60 , 48 , 72
Step-by-step explanation:
Third angle = of right angle
Ratio of two angles = 2 : 3
The two angles are 2x , 3x
2x + 3x + 60 = 180 {Angle sum property of triangle}
5x + 60 = 180 {Subtract 60 from both sides}
5x = 180 - 60
5x = 120
x = 120/5
x = 24
2x = 2* 24 = 48
3x = 3*24 = 72
