Multiply the first digit by 3 then subtract the answer by 2. Rule: x 3 - 2
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!
3/4 ( (-50+2)/5)
= 3/4 ( -48/5)
= 3/4 * -48/5
= -36/5
