Classic trigonometry problem that demonstrates the spirit of the UVM Math Contest. Do you remember your angle formulas?

Difficulty: medium, if only because of the time pressure.

Difficulty: Pretty easy, once you see where you're going.

Standard instructions for this series: No calculator allowed. Express answers in reduced form. Rationalize denominators. Radicals must be reduced. All numbers are base ten unless otherwise specified. Do not approximate radicals or π. Leave such answers as 1025π or √39, for example. Source: UVM Math Contest 2013
