Right Triangle, and the ratio between the sides is important if you are interested in just finding the angles.

4%5E2%2B1%5E2=h%5E2
h=sqrt%2817%29

More than one way to go.
Law of Sines?

sin%2890%29%2Fh=sin%28alpha%29%2F4=sin%28beta%29%2F1

sin%2890%29%2Fsqrt%2817%29=sin%28alpha%29%2F4=sin%28beta%29%2F1
