Begin sketching (see below): 1. Place A anywhere. At A draw a vertical north/south line. Point B is at $55^{o}$east of south. 2. At B draw a vertical north/south line. Point C is at $35^{o}$from north 3. The angle at B is made of two parts, x and y, in total $90^{o}$ 4. ABC is a right triangle, Pythagorean Theorem applies. $d=\sqrt{81^{2}+74^{2}}\approx 108.9771$ .
