How do you find the bond angles like in these questions?

2E.17 Predict the bond angles at the central atom of the following molecules and ions: (a) ozone, O3; (b) azide ion, N32; (c) cyanate ion, CNO2; (d) hydronium ion, H3O1.

It depends on the shape of the molecule (i.e. trigonal planar, tetrahedral, etc.). You determine the shape based on the number of atoms and the number of lone pairs on the central atom.

Try searching up bond angle charts! First determine the VSEPR structure then you can find out what angle the bonds are at.
