Answer

See the answer below.

Work Step by Step

a) Sulfur is bonded to two atoms and has two lone pairs, it's in a bent geometry from the tetrahedral archetype so this bond angle is approximately 109$^{\circ}$. b) The central atom is in a linear geometry without lone pairs so this bond angle is approximately 180$^{\circ}$. c) The central carbons in angles 1 and 2 are in a trigonal planar geometry, so these bond angles are approximately 120$^{\circ}$. The oxygen in angle 3 is in a bent geometry from the tetrahedral archetype so this bond angle is approximately 109$^{\circ}$.
