Question

the triangle on the right is a scaled copy of the triangle on the left. identify the scale factor. express your answer as a fraction in simplest form.

Explanation:

Step1: Recall scale - factor formula

The scale factor $k$ from the original figure to the scaled - copy is given by the ratio of the corresponding side lengths of the scaled - copy to the original figure. Let the side length of the original triangle be $a = 85$ and the side length of the scaled - copy be $b = 8$.

Step2: Calculate the scale factor

$k=\frac{b}{a}=\frac{8}{85}$

Answer:

$\frac{8}{85}$
