Generally a problem such as mine would be quite easy, but instead of given constants, I'm given two trigonometric functions:
From this I've gathered:
(Opposite side length)
(Adjacent side length)
(Hypotenuse side length)
However I have no clue as to how to go from here. Using the law of cosines would bring me no where I believe. Care to correct me? :P
If it isn't obvious enough already, I'm supposed to solve for .
