I don't know how to find x. Can someone please explain.

Answer:
x° = 109°
Step-by-step explanation:
x° is a "corresponding angle" to either of the upper left or lower right interior angles of the parallelogram. (The lines marked with a single arrow are parallel, as are the lines marked with a double arrow.)
Either of those angles is supplementary to the one marked 71°, so x° and all corresponding angles are 180° -71° = 109°.
