Question

the pair of figures is similar. find the missing side. x = 4 x = 5 x = 20 x = 12

Explanation:

Step1: Set up proportion

Since the triangles are similar, $\frac{3}{12}=\frac{x}{20}$.

Step2: Cross - multiply

$12x = 3\times20$.

Step3: Solve for \(x\)

$12x=60$, so $x=\frac{60}{12}=5$.

Answer:

$x = 5$
