Aabc is an isosceles triangle. ab is the longest
side with length 11x +4. bc = 5x + 4 and ca =
4x + 7. find ab.

In a isosceles triangle, two sides are equal. Here, AB is already mentioned longest side. So, BC and CA must be equal.

Now,

BC =CA

or, 5x+4 = 4x+7

or, x = 3

AB = 11x+4 = 11×3+4 = 37.
