Question

1. if the scale factor of figure a to figure b is 4:5, find the value of x. x = _ type your answer...

Explanation:

Step1: Set up proportion

Since the scale factor of figure A to figure B is \(4:5\), we have \(\frac{x}{15}=\frac{4}{5}\).

Step2: Solve for \(x\)

Cross - multiply: \(5x = 4\times15\). Then \(5x=60\), and \(x=\frac{60}{5}\).

Answer:

\(12\)
