Use the image below to answer the following question: A right triangle is shown. The two angles that are not 90 degrees are marked x and y. The leg across from angle y measuring 3, another leg across from angle x measuring 4, and the hypotenuse measuring 5.

What relationship do the ratios of sin x° and cos y° share?

The ratios are opposites. (4 over 5 and negative 4 over 5)
The ratios are both negative. (negative 4 over 5 and negative 4 over 5)
The ratios are both identical. (4 over 5 and 4 over 5)
The ratios are reciprocals. (4 over 5 and 5 over 4)
