Question

These two polygons are similar.

Answer 1

Explanation:

Answer 2

`\huge\boxed{z=3}`

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:

`(z)/(9)=(2)/(6)` cross multiply

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

`6z=18` divide both sides by 6

`z=3`
