If I know the geometry of the triangle base, that is lengths a, b, c, angles A, B, C.
I know the angles of lines x, y, z, but do not know the lengths of x, y, z, how do I calculate the height of the pyramid and therefore D?
This an oblique pyramid.
Following finding D I can calculate the volume, however I am totally stumped at finding the apex. All equations I've found so far require a height.
