Best ResponseYou've already chosen the best response.2The sine, cosine, and tangent ratios of a right triangle are as follows: \(\sin A = \dfrac{opp}{hyp} \) \(\cos A = \dfrac{adj}{hyp} \) \(\tan A = \dfrac{opp}{adj} \)

Best ResponseYou've already chosen the best response.2Look at the figure above. For angle A, leg AC is called the adjacent leg. For angle A, leg BC is the opposite leg. The hypotenuse is side AB.

Best ResponseYou've already chosen the best response.2According to the definition of sine, \(\sin A = \dfrac{opp}{hyp} \) the sine of angle A is the ratio of the lengths of the opposite leg to the hypotenuse. That means that for the figure above, \(\sin A = \dfrac{BC}{AB} \)

Best ResponseYou've already chosen the best response.2Now let's look at your problem. We are asked what the ratio r/p is equal to.

Best ResponseYou've already chosen the best response.2r and p are legs of the triangle. The only ratio (of sin, cos, and tan) that deals only with the lengths of legs (and not the hypotenuse) ids the tangent ratio. \(\tan A = \dfrac{opp}{adj} \) The tangent ratio is the ratio of the lengths of the opposite leg to the adjacent leg.

Best ResponseYou've already chosen the best response.2The ratio r/p must be a tangent because it involves only lengths of legs. Since the ratio r/p must be a tangent, it must be equal to \(\dfrac{opp}{adj} \) Now we look in the figure, and we see which angle is opposite leg r? It is angle y. Also, we look in the figure and we see that leg p is the adjacent leg top angle y. The means we must have the tangent of angle y.
