Question

$\triangle bcd \sim \triangle vwx$. find $cd$.

Explanation:

Step1: Find similarity ratio

$\text{Ratio} = \frac{BC}{WX} = \frac{5}{20} = \frac{1}{4}$

Step2: Set up proportion for CD

$\frac{CD}{VX} = \frac{1}{4}$

Step3: Solve for CD

$CD = VX \times \frac{1}{4} = 16 \times \frac{1}{4}$
