Homework Statement
Can someone help me to find angle between 2 lines in 3D? I have 2 lines from (-x, 0, -y) to (0, 0, 0) to (0, x, y). I can use CAD to get the answer. But my shop guys will need some kind of formula. The easier way please, thank all.

Example: (-10, 0, -6) to (0, 0, 0) to (0, 10, 6) is 105.3 degree.
