cos^(2)alpha+cos^(2)beta+cos^(2)gamma+cos^(2)delta=(4)/(3)

A line makes angles alpha, beta, gamma, delta with the diagonals of a cube, prove that cos^2alpha + cos^2beta + cos^2gamma + cos^2 delta = 4/3

If the line makes angles alpha, beta, gamma, delta with four diagonals of a cube, then the value of cos^(2) alpha+cos^(2) beta+cos^(2) gamma+cos^(2) delta is equal to m/3 . Find m.
