I am unable to follow your description of the problem (I have no idea what you mean by "Assume a pole AB with Point C and D on 2 sides of it"). It would really help if you could post a figure. Nevertheless, since you have one length given, have the various angles and want to find the length of another side of one of the triangles, you should be able to use the Law of Sines - for any triangle with side lengths A, B and C and angles a, b, and c:
I'm guessing that from the figure you should be able to relate the 200' length of CD to the length of one of the sides of the triangle ABC or ABD. in order to determine length AB.
