Answer:

4

Step-by-step explanation:

As, the measure of one congruent side is = 2x + 3

So, bc there are 2 congrent sides, =( 2x + 3) + (2x +3) = 4x + 6

Now perimeter= the length of the 2 sides + third side

Perimeter = (4x + 6) + (7x) = 50 cm

So, 11x + 6 = 50

So, 11x = 50 - 6 = 44

11x = 44

x = 44/11

x = 4cm.
