Question

the figures below are similar. use proportions to find the length of s. s = ?

Explanation:

Step1: Set up proportion

Since the figures are similar, the ratios of corresponding sides are equal. So we have $\frac{6}{9}=\frac{8}{s}$.

Step2: Cross - multiply

$6s = 9\times8$.

Step3: Simplify right - hand side

$6s=72$.

Step4: Solve for s

$s=\frac{72}{6}$.

Answer:

$12$
