Can someone answer. there is one problem. there's a picture. you!

Excellent question.

First since Cot is the opposite of Tan we must first find Tan.

The formula for Tan is Opposite/Adjacent, in this case that would be 9/12.
Now to get Cot we must flip 9/12 to get 12/9.
Finally we simplify by dividing the top and bottom by 3 to get 4/3.

The answer here is 4/3!

Hope this helps (:
