      The basic trig functions are defined as ratios of the sides of the triangle as the legs relate to θ (either adjacent to it or opposite it). ... (15°) = 12/h so h = 12/cos(15). To finish, we need the cosine of 15 degrees which requires a calculator. This tells us cos(15°) is about .966 so. h = 12/.966 = 12.42. We now have two out of three ...
