Use proportions to find the missing side length ( x ) in the two similar figures.

In similar figures, corresponding sides are in proportion. This means we can set up a proportion to find the missing side length (x).

Let's say we have two similar figures, one with side lengths a and b, and the other with side lengths c and x.

We can set up the proportion:

a/b = c/x

Now, we can cross multiply to solve for x:

a * x = b * c

To find x, we divide both sides by a:

x = (b * c) / a

This formula can be used to find the missing side length (x) in two similar figures.
