The figure presents 2 parallel lines l and m, which are almost horizontal, with l above m. A line segment from the left on m, moves up and to the right, intersects, and ends above l. Another line segment from the right on m, moves up and to the left, intersects, and ends at the same point as the other line segment, above l. The angle at the point where the two line segments meet is labeled x degrees. The angle above l and to the left of the right line segment is labeled z degrees. The angle above m and to the right of the left line segment is labeled y degrees. The figure is not drawn to scale

In the figure above, lines l and m are parallel, y equals 20, and z equals 60. What is the value of x ?
