Question

These two polygons are similar.

Answer 1

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:

$\dfrac{z}{9}=\dfrac{2}{6}$         cross multiply

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

$6z=18$         divide both sides by 6

$z=3$
