we can use similar polygons. We realize that the polygon with area $x$ is similar to the pentagon. We can a,so notice that the $z$’s ams $y$’s form a circle around $x$, with five zs and five ys. So similarly in the pentagon $x$, there will be 5 zs and five ys, but the ys and zs are $\frac{1}{5}$ each of the original zs and ys in the larger pentagon. Now I’m confused if there is a specific value of $x$, not given in the question?
