Answer: I can't give you the answer, but I can tell you how to solve it. To problems like these I use the acronym "SOH CAH TOA."
To find sine of something you divide the opposite side by the hypotenuse.
To find Cosine of the triangle you do the adjacent side divided by the hypotenuse.
To find tangent of the triangle, you take the opposite side and divide it by the adjacent side.
