Hmmm.  This isn't a solution really, but maybe something to lead you to
one?  Since any triangle may be divided into two right-triangles, maybe
you could do that.  With a right triangle, its a simple matter of
trigonometry to figure how far a point is from the vertical "stem" given
the hieght along the stem, ie:
    
                  /|
                 / |
  this point->  /  | <- at this height
               /   |
              /    |
             /_____|

Then you could position the sphere randomly between the "stem" and the
hypotenuse.

Hmm.  A thought, anyway.
