Question

what is the scale factor from the original figure to the scaled copy? original 12 10 scaled copy 36?

Explanation:

Step1: Recall the formula for scale factor

Scale factor \(=\frac{\text{Dimension of scaled copy}}{\text{Dimension of original}}\)

Step2: Identify corresponding dimensions

The height of the original triangle is \(12\), and the height of the scaled - copy triangle is \(36\)

Step3: Calculate the scale factor

Scale factor \(=\frac{36}{12}\)
\(=\ 3\)

Answer:

\(3\)
