Question

these shapes are similar. find x.

Explanation:

Step1: Set up proportion

Since the shapes are similar, the ratios of corresponding sides are equal. So, \(\frac{15}{45}=\frac{5}{x}\).

Step2: Cross - multiply

Cross - multiplying gives \(15x = 5\times45\).

Step3: Solve for \(x\)

First, calculate \(5\times45 = 225\). Then, \(x=\frac{225}{15}\).

Answer:

\(15\)
