Final answer:
To find the missing side length of similar polygons, set up a proportion using the given side lengths and solve for the missing side length.
Step-by-step explanation:
To find the missing side length, we need to apply the concept of similar polygons. Similar polygons have corresponding angles that are equal and corresponding sides that are proportional.
In this case, let's say the ratio of the corresponding sides in the two polygons is x:y. We are given the length of one side in the first polygon and need to find the length of the corresponding side in the second polygon.
We can set up a proportion using the given side lengths:
Length of the given side in the first polygon / Length of the corresponding side in the second polygon = Ratio
Solving the proportion, we can find the missing side length.
