In a parallelogram opposite sides have the same length therefore, for figure EFGH to be a parallelogram we must have that:


GF=HE

Substituting we get:


z+10=2z

Now, we solve for "z". First, we subtract "z" from both sides:


\begin{gathered} z-z+10=2z-z \\ 10=z \end{gathered}

Therefore, the value of "z" is 10.
