For these you just draw the lewis structures and from the lewis structures you determine the shapes based on lone pairs and bonds around the central atom and from the shape you can estimate the bond angle
For example, for part a) S2O3 2- has a central S atom bonded to the 4 other atoms with no lone pairs around the central S resulting in a tetrahedral shape with bond angles of 109.5degrees

What's the correct lewis structure for S2O3 2-? I know that the double bonds don't matter for the shapes and bond angles, but I'm getting varied answers on the internet.
