Trig help

[needshelp]

Hello my question is:

Application: Two forest fire towers, A and B are 20.3km apart. The bearing from A to B is N70E. The ranger in each tower observes a fire and radios the fire's bearing from the tower. The bearing from tower a is N25E. From tower B, the bearing is N15W. How far is the fire from each tower?

I kind of know how to do this problem, but I just can't picture what the picture would look like in my head. I know the reason I can't get the answer is something is wrong with my picture.

Thanks for your time

If you have a question regarding the reply you received, please reply (there) with that question. (If you just re-post the exercise somewhere else, you're very likely to receive an answer very similar to the one you didn't understand the first time.)

Thank you for your consideration.
