Can you upload another picture, you cannot really see your problem
Obtuse angles are over 90 degrees but less than 180 degrees. So minimum y can be is 10: (5 x 10) + 45 = 95 degrees (which is more than 90). Maximum for y is 26: (5 x 26) + 45 = 175 (which is less than 180 degrees)
Hey there,
The answer is: 18a^3b2/2ab=9a^2*b
