In the sulfur trioxide molecule (SOS), each of the three oxygens are bonded to the central sulfur atom via a double bond, which places them in a trigonal planar arrangement. The O-S-O bond angle is therefore the angle between two of these bonds, and as a result is 120 °. The rest of the molecule is irrelevant to this question.
