Question

the right triangle on the right is a scaled copy of the right triangle on the left. identify the scale factor. express your answer as a fraction in simplest form.

Explanation:

Step1: Recall the formula for scale factor

Scale factor \(=\frac{\text{length of side in new figure}}{\text{length of corresponding side in original figure}}\)

Step2: Identify the corresponding sides and calculate

The original side length is \(4\), and the new (scaled - copy) side length is \(7\). So, scale factor \(=\frac{7}{4}\)

Answer:

\(\frac{7}{4}\)
