**MathMate**, Sunday, January 30, 2011 at 11:47amLet the sides be A, A and B.

A being one of the equal sides, and B the third side.

"an isosceles triangle has a perimeter of 136 inches."

means that

A+A+B = 136 .... (1)

and

"If one of its equal sides measures 42 inches"

means A=42, this makes equation (1):

42+42+B = 136

and we look for the value of B.

Can you take it from here?
