Question

AABC is an isosceles triangle. AB is the longest
side with length 11x +4. BC = 5x + 4 and CA =
4x + 7. Find AB.

Answer 1

Answer:

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.
