The definition of the sine ratio is the ratio of the length of the opposite side divided by the length of the hypotenuse. Well, the length of the side opposite ∠C is the length of the hypotenuse, so sin ∠C = c/c = 1 Because ∠C is a right angle, m∠C = 90º, so sin 90º = 1. Figure 20.5 A right triangle with tan ∠A = 5/12.
