Question

if these two shapes are similar, what is the measure of the missing length q? q q = inches

Explanation:

Step1: Set up proportion

For similar shapes, the ratios of corresponding sides are equal. So we have the proportion $\frac{q}{5}=\frac{2}{1}$.

Step2: Solve for $q$

Cross - multiply to get $q\times1 = 5\times2$. Then $q = 10$.

Answer:

10
