Question

the polygons are similar. find the value of $x$.
$x = \square$

Explanation:

Step1: Find similarity ratio

$\text{Ratio} = \frac{DF}{GJ} = \frac{16}{12} = \frac{4}{3}$

Step2: Set up proportion for $x$

$\frac{x}{15} = \frac{4}{3}$

Step3: Solve for $x$

$x = 15 \times \frac{4}{3} = 20$

Answer:

20
