## Homework Equations

trig and inverse trig functions?

## The Attempt at a Solution

I have no idea how to solve this. When I try and use the trig that I know to find the lengths, I also end up having to depend on other variables.

The only thing I was able to find out is that the angle opposite the 12 is twice the that of the 6.
