Question

Each pair of polygons is similar. Write and solve a proportion to find each missing side measure.

Answer 1

9. x = 2

Explanation:

9. The corresponding side lengths of two similar polygons are proportional to each other. This means the ratio of their corresponding side lengths are equal.

Thus:

8/x = 12/3

8/x = 4

Cross multiply

4x = 8

4x/4 = 8/4

x = 2
