Question

both figures are similar. find the missing side.

Explanation:

Step1: Set up proportion

For similar figures, the ratios of corresponding sides are equal. So we have $\frac{4}{x}=\frac{10}{70}$.

Step2: Cross - multiply

$10x = 4\times70$.

Step3: Solve for x

$10x=280$, then $x=\frac{280}{10}=28$.

Answer:

28
