What are the bond angles in the central atom of the following: NSF, OF2, and IBr?2

NSF molecule

There is a lone pair on the N atom, a lone pair on the S atom, and there are three lone pairs on the F atom. The electron geometry is trigonal planar and the molecular shape is bent.

The theoretical bond angle is 120 °, but repulsion by the lone pairs decreases the bond angle to about 117 °.

OF2

The electron geometry is tetrahedral and the molecular shape is bent.The theoretical bond angle is 109.5 °, but repulsions by the lone pairs decrease the bond angle to about 103 °.

IBr-2

The electron geometry is trigonal bipyramidal. The lone pairs occupy the equatorial positions, with the Br atoms in the axial locations. The bond angle is 180 °.
