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 concept

The scale factor is used to find lengths in the scaled - copy. Given scale factor \(k = 2\).

Step2: Identify corresponding side

The side of length 5 in the original triangle corresponds to the missing side in the scaled - copy.

Step3: Calculate missing length

Multiply the original side length by the scale factor. Let the original side length be \(a = 5\) and scale factor \(k=2\). The length in the scaled - copy \(b=k\times a\). So \(b = 2\times5=10\).

Answer:

10
