can anyone help with part (a)? I was getting 0,180, 360, but the answer at the back is 180 only. It could be a typo, but just wanna make sure.

how would you sketch the graph of y=csc(2x-pi) for -2pi<x<2pi? wouldn't the graph be the same as y=csc(2x) since the period is pi so graph will shift pi units to the right and it should stay the same, right?

exactly!!! But whyy?
open this website and read each and every detail there given of the graph of how he generalized the equation and how the phase shift was calculated.
if you still don't understand it than ask here again.

do the same for the other equation csc(2x)
I didnt know thats how you get the phase shift. I first sketched the graph of y=csc(2x) and then shifted it pi units to the right (y=csc(2x-pi)) is this wrong? I've been doing this for a long time and always got the right answers.
