Question

the pair of figures is similar. find the missing side.
x = 10
x = 4
x = 5
x = 2

Explanation:

Step1: Set up proportion

Since the triangles are similar, the ratios of corresponding sides are equal. So, $\frac{5}{x}=\frac{4}{8}$.

Step2: Cross - multiply

Cross - multiplying gives $4x = 5\times8$.

Step3: Solve for \(x\)

$4x=40$, then $x=\frac{40}{4}=10$.

Answer:

$x = 10$
