Hint: Start with a circle inscribed inside a triangle

My work

Okay, my diagram is in the attachment.
Sorry that was my first post and I didn't know the rules.
Anyways, I've found out very little, and I don't even know if it will help in the long run... :???:
The height of the "trapezoid" is 6. The tangents of the circle are the same lengths, and that's all I have.
