Question

rstuv ~ dcbfe. find rv.

Explanation:

Step1: Find similarity ratio

$\text{Ratio} = \frac{ST}{CB} = \frac{2}{20} = \frac{1}{10}$

Step2: Match corresponding sides

Corresponding side to $RV$ is $ED = 40$

Step3: Calculate $RV$

$RV = ED \times \text{Ratio} = 40 \times \frac{1}{10} = 10$

Answer:

10
