# CCSS IP Math II 5.4.4 Example 3

To find the distance across a pond, Rita climbs a 30-foot observation tower on the shore of the pond and locates points $A$ and $B$ so that $\overline{AC}$ is perpendicular to $\overline{CB}$. She then finds the measure of $\overline{DB}$ to be 12 feet. What is the measure of $\overline{AD}$, the distance across the pond?
