Question

the scale factor is the number you multiply each length in the original figure by to get the corresponding length in the scaled copy. the scale factor is 2. what is the missing length in the scaled copy? units

Explanation:

Step1: Recall scale - factor formula

The formula to find the length in the scaled - copy is $l_{scaled}=k\times l_{original}$, where $k$ is the scale factor and $l_{original}$ is the length in the original figure.

Step2: Identify original and scale - factor values

The scale factor $k = 2$ and the corresponding original length for the missing side is $5$ (from the original triangle).

Step3: Calculate the missing length

$l_{scaled}=2\times5$
$l_{scaled}=10$

Answer:

10
