Hi, can you help me to solve this exercise, please!!!

CD = 18
Explanation:Parameters:
Angle = 60 degrees
Opposite = 18√3
To find CD, we use the ratio:
[tex]\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}[/tex]
