Answer:

\large\boxed{\dfrac{50}{3}}

Step-by-step explanation:

If the polygons are similar, then the corresponding sides are in proportion:

\dfrac{z}{10}=\dfrac{20}{12}        <em>cross multiply</em>

12z=(10)(20)

12z=200         <em>divide both sides by 12</em>

z=\dfrac{200}{12}\\\\z=\dfrac{200:4}{12:4}\\\\z=\dfrac{50}{3}
