In the cube

A B C D E F G H

with

S_{A C}

being the midpoint of the diagonal

A C

, let

φ

be the angle between the line

E G

and the line

G S_{A C}

. Choose the correct expression for

φ

:

tg φ = \sqrt{2}

\sin φ = \frac{\sqrt{3}}{3}

tg φ = \frac{\sqrt{2}}{2}

\cos φ = \frac{\sqrt{6}}{3}
