Now we have a spherical triangle, ABC which has sides a, b, and c. There are ways to solve this triangle using spherical trig. Here are a couple of Wolfram sites:
http://mathworld.wolfram.com/SphericalTrigonometry.html http://mathworld.wolfram.com/NapiersAnalogies.htmlWe have all the side lengths, a, b, and c - these are the angles between points B and C, between points A and C, and between points A and B as subtended at the center of the earth. A, B and C also represent the angles between azimuths from a point to the other points on the triangle. Since we have a, b, and c, we can find A, B, and C.
