Question

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

Answer 1

In order to determine the length of side CD, use the tangen of 60 degrees as follow:

`\tan 60=\frac{18\sqrt[]{3}}{CD}`

Solve the previous expression for CD and simplify, as follow:

`CD=\frac{18\sqrt[]{3}}{\tan 60}=\frac{18\sqrt[]{3}}{\sqrt[]{3}}=18`

Hence, the length of side CD is 18
