Question

Hints:

1. In general, when two triangles are similar, the ratio of two sides of one triangle, equals the ratio of the corresponding sides of the other triangle

2. In this case, $\frac{AC}{BC} = \frac{XZ}{YZ}$, so in other words, 

$\frac{6}{9} = \frac{x}{3}$

3. Solve for x to get the length of XZ

All you have to do is solve the proportion for x. You do know how to solve proportions, don't you?
