Question

what is the scale factor from the original figure to the scaled copy? original scaled copy 10? 12 36 an error has occurred. please enter a number.

Explanation:

Step1: Recall scale - factor formula

The scale factor $k$ from the original to the scaled - copy is given by the ratio of corresponding side lengths of the scaled - copy to the original. For two corresponding side lengths $a$ (in the scaled copy) and $b$ (in the original), $k=\frac{a}{b}$.

Step2: Identify corresponding side lengths

We know that one side of the original is $b = 12$ and the corresponding side of the scaled copy is $a = 36$.

Step3: Calculate the scale factor

Using the formula $k=\frac{a}{b}$, we substitute $a = 36$ and $b = 12$. So, $k=\frac{36}{12}=3$.
