Question

polygon k is a scaled copy of polygon j. what scale factor takes polygon j to polygon k?

Explanation:

Step1: Select corresponding sides

We can use the top - side lengths of the two polygons. Side length of polygon J is 8.6 and of polygon K is 12.9.

Step2: Calculate scale factor

The scale factor $s$ is found by dividing the length of the corresponding side of the scaled - copy (polygon K) by the length of the original side (polygon J). So $s=\frac{12.9}{8.6}$.
\[s = 1.5\]

Answer:

1.5
