These two polygons are similar.
Jet001 [13]

Answer:

\huge\boxed{z=3}

Step-by-step explanation:

If two polygons are similar, then corresponding sides are in proportion.

The corresponding sides:

4 → x

y → 15

3 → w

2 → 6

z → 9

therefore:

\dfrac{z}{9}=\dfrac{2}{6}         <em>cross multiply</em>

(z)(6)=(9)(2)

6z=18         <em>divide both sides by 6</em>

z=3
