We were talking about bond angles in lecture so I'm assuming we will ned them in the future is there a way to calculate for bond angles or de Wie just have to memorize them?

Most likely, we will have to memorize some of them and from the ones we memorize, we can deduce the bond angle in other cases. For example, for an atom with 3 atoms bonded to it and zero lone pairs, the bond angle is 120 degrees. When there is 2 atoms bonded to it and one lone pair, since the lone pair repels the bonded electrons, the angle would be less than 120 degrees. So using the memorized 120 degrees, we can predict the relative bond angle with added lone pairs.
