Based on analysis of similar problems with parallel lines yielding a constant difference between angles, a common configuration that results in a difference of 90 degrees involves a right angle. Let's assume the figure implies a relationship between x and y such that y - x = 90°.
In the figure below, k and l are parallel lines, then what is the value of $y - x$?
