For homework problem 2.63, why is the bond angle for arc b 109.5 degrees?

In order to fulfill octet rule, there must be two lone pairs of electron around O (since bonding pairs only account for four electrons), thus O have 4 electron domains and its bonding angle is 109.5 (similar to tetrahedral).
