I have a right triangle in which i know sides a,b, and c:
Code:
             1
            /|
           / |
     a   /   |
        /    |   c
       /     |
      /      |
   2 /______ |3
          b
I need to find 1, 2, and 3

3 is obviously 90, and if i can find one other, i can find the third, so i was thinking about using ArcCosin. But i am new at Trig, so i'm really not sure. (This needs to be done in VB)
