your answer is incorrect
find the length x.

Explanation:

Step1: Set up proportion using similar - triangles

Since the two right - triangles are similar, the ratios of their corresponding sides are equal. Let the two similar right - triangles have side lengths such that $\frac{x}{3}=\frac{7}{6}$.

Step2: Solve the proportion for $x$

Cross - multiply to get $6x = 3\times7$, then $6x=21$. Divide both sides by 6: $x=\frac{21}{6}=\frac{7}{2}=3.5$.

Answer:

$3.5$
