S has 6 valence electrons. In $SF_4$: 4 bonding pairs + 1 lone pair = 5 electron domains.

$$Electron geometry: Trigonal bipyramidal$$

$$Molecular geometry: See-saw (seesaw)$$

Bond angles: $\approx 101.6°$ (axial–equatorial) and $\approx 173°$ (axial–axial), both compressed from ideal due to lone pair repulsion.

$$See-saw shape; bond angles \approx 101.6° and 173°$$

Saved me before my mock test. Much clearer than my coaching notes.

How do we know the approximation is valid here?

Underrated solution. The way you set it up makes it almost obvious.
