Find the value of $x$x in the parallelogram below.

A parallelogram with its top and bottom sides marked with double arrowheads, indicating that these sides are parallel, and its left and right sides are marked with a single arrowhead, indicating that they are also parallel. The angles at the upper-right and the bottom-left vertices of the parallelogram are both labeled "$79$79º," indicating their measures. The angle at the lower-right corner of the parallelogram is labeled "$x$xº," indicating its measure.

Enter each line of work as an equation.
