Deviation from ideal bond angles | Molecular Geometry

What is the angle of the following molecules:

SeF6, BrF3, SbCl3 and GeCl4?

SeF6 ⇒ AX6 ⇒ angle FSeF = 90°

BrF3 ⇒ AX3E2 ⇒ T-shaped so angle = 90° but lone pairs effect ⇒ angle FBrF < 90°

SbCl3 ⇒ AX3E ⇒ trigonal pyramidal so angle = 109.5° but lone pairs effect ⇒ angle ClSbCl < 109.5°

GeCl4 ⇒ AX4 ⇒ tetrahedral ⇒ angle ClGeCl = 109.5°
