Explanation:
We defined cosine of theta to be the side adjacent to theta divided by the hypotenuse. And by adjacent we mean the side that's next to theta, this is the hypotenuse the long side of the right triangle and so that means x over z. The sine is defined as the side opposite theta y over the hypotenuse, so y over z
