Answer

120 degrees; 109.5 degrees

Work Step by Step

The molecular geometry is trigonal planar, for there are three electron domains around the central atom, and none of them are lone pairs. Thus, we use a table to find that the first angle is 120 degrees. The molecular geometry of the second angle is tetrahedral, so its angle is 109.5 degrees.
