Since the side of length 28 touches angle x, it is called the ​ (a)   side to angle x. Since the side of length 41 is across from the right angle, it is the ​ (b)   of the triangle. If we set up the ratio ​ 28/41 that is the​ (c)   of 25.

The side marked x is ​ (a)   to the angle that is 56 degrees. The side marked 20 is the ​ (b)   of the right triangle since it is across from the right angle. If we set up the ratio ​ x/20, we would be finding ​ (c)   56.

We can find the length marked y using the tan function which is the ratio of ​ ​ (a)   . So we write tan (45) = ​ (b)   ​ . We can find x using the cos function and set up and solve the proportion ​​ (c)   45 = ​​ (d)   .
