# How can I find the bond angles for carbamic acid?

I need to find the bond angles for carbamic acid (as a self-given practice). As I understand it, the structure looks like this:

        O
||
H - N - C - O - H
|
H


I'm trying to find the O-C-O bond angle, but I'm not sure how the - H on the end will factor in to the answer. Everything I read about it is dense and fairly hard to understand.

I've tried finding the number of electron domains around the C atom (I think it's 4), but I'm not sure where to go from there.

What is the general procedure for doing this? How would it look if I were trying to find a different angle (like H-N-H)?
