Question

what is the scale factor from the original figure to the scaled copy? 34 10 original? 20 scaled copy

Explanation:

Step1: Recall scale - factor formula

The scale - factor $k$ from the original figure to the scaled copy for similar figures is given by the ratio of corresponding side - lengths. Let's assume the corresponding sides are the vertical sides here.

Step2: Calculate the scale - factor

The length of the vertical side of the original figure is $10$, and the length of the vertical side of the scaled copy is $20$. The scale - factor $k=\frac{\text{length of side in scaled copy}}{\text{length of corresponding side in original figure}}=\frac{20}{10}$.
$k = 2$

Answer:

$2$
