Answer:

CD = 18

Step-by-step explanation:

Parameters:

Angle = 60 degrees

Opposite = 18√3

To find CD, we use the ratio:


\begin{gathered} \tan \theta=\frac{\text{Opposite}}{\text{Adjacent}} \\ \\ \tan 60=\frac{18\sqrt[]{3}}{CD} \\ \\ CD=\frac{18\sqrt[]{3}}{\tan 60} \\ \\ =\frac{18\sqrt[]{3}}{\sqrt[]{3}}=18 \end{gathered}
