From city A to city B, a plane flies 650 miles at a bearing N48degreesE. From city B to city C the plane flies 810 miles at a bearing S36degreesE. Find the return distance from C to A and the bearing from C to A.

I'm unsure of if I use 36 degrees as the angle measure for B. I believe 42 degrees would be angle A's measurement. If this is correct, I got 711.5293 miles from city C to A using the Law of Sines. How would I go about finding the bearing from C to A?

Thanks!
