This is confusing me.. I already solved most of my problem, solving for x and y, but now I need to know whether this triangle is acute or obtuse. It has two acute angles, yet an obtuse angle also. Which is it? Why? How do I know if another triangle is acute or obtuse?

Prove this identity:

tan^2(α)-sin^2(α)=sin^2(α)*tan^2(α)

*this is not tan^2α,this is tan(α)*tan(α)
