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>

$z=3$
