Step-by-step explanation:
If you have any questions about the way I solved it,don't hesitate to ask
NO. It's FALSE.

therefore 0.3801 > 0.3711
Total Unit of Triangle = 2+4+9 = 15
Value of one unit = 180/15 = 12
So, Angles = 2(12) : 4(12) : 9(12) = 24 : 48 : 108
In short, Your Angles would be: 24, 48 & 108
Hope this helps!
