Question

the figures below are similar. use proportions to find the length of n. 4 8 6 n n = ?

Explanation:

Step1: Set up proportion

Since the figures are similar, the ratios of corresponding sides are equal. So we have $\frac{4}{6}=\frac{8}{n}$.

Step2: Cross - multiply

$4n=6\times8$.

Step3: Simplify right - hand side

$4n = 48$.

Step4: Solve for n

$n=\frac{48}{4}=12$.

Answer:

$n = 12$
