| |  Pre/cal Trig class - bearing problem
Hi, this is my first time posting. I get most of this easily, but I just cannot draw the picture correctly for this particular problem.
Two fire lookouts are located 12 miles apart. Lookout A is at a bearing of N32W of lookout B. A fire was sighted at a bearing of S79E from A and N67E from B. Find the distance of the fire from lookout B.
I appreciate your speedy help! I just need the picture, then I'll apply either Law of Sines or Law of Cosines to find the distance I need. Paula |

Well, you rock 
After applying the law of sines, I wound up with lookout B approx. 15.69448 miles from the fire. I got very frustrated with the angles around lookout A.
