The value of x that makes lines a and b parallel is 76°.

This is because when two parallel lines are cut by a transversal, the alternate angles formed by the transversal are equal. In the figure below, the angle x is an alternative interior angle to the angle measured 76°, so they are equal. That is, x = 76° (provided that line a is parallel to line b)
