DECI-LON: an Instruction Manual. Using this law and the method of solving proportions explained in $39, we can solve any triangle for which a side, the opposite angle, and another part are given. Example 1. Given a triangle (see Fig. 19) in which a = 50, A = 65Ad, and B = 40Ad, find b, c, and C. Solution. Since A + B + C = 180Ad, C = 180Ad a (A + B) = 75Ad. Application of the law of sines to the triangle gives S sin 65Ad sin 40Ad sin 75Ad D 50 b c 40Ad b=35.5 Accordingly (see Fig. 20), opposite 50anbsp;...
