We know that the trigonometric identity that uses the adjacent side and the hypotenuse is cosine. We can set this up as:

We need to solve for x, so let's isolate it:

So,
x = 10.2 units
They are both periodic functions that look like waves. They both have a period of 2pi and oscillate between 1 and -1.
