Let \( ABCDEFV \) be a regular hexagonal pyramid with a base edge length of \( 4\,\mathrm{cm} \) and a height of \( 6\,\mathrm{cm} \). Let \( \varphi \) be the angle between the plane \( AFV \) and the base plane \( ABC \) (see the picture). Choose the correct expression for \( \varphi \):
\( \mathrm{tg}\,\varphi=\sqrt3 \)
\( \sin\varphi=\sqrt3 \)
\( \mathrm{tg}\,\varphi=\frac{\sqrt3}3 \)
\( \mathrm{tg}\,\varphi=\frac32 \)
