Look at this diagram to see how this works. A lake between Towers A and C makes it difficult to measure the distance between them directly. In order to find the distance along the northern triang,es, you need the measure of the third angle in the triangle.

What proportion do you get when you eliminate j? Label the length of the side riht A as a, the length of the side opposite B as b, and the length of the side opposite C as c.
