This is almost the same circuit as the one here (only R and C are swapped).

Start by understanding one circuit, then move on to the next and apply your freshly acquired knowledge to the new circuit.

Think about what the time constant is with these two components. Then convert that into a phase angle.

Time constant is RC=0.05m. how to convert that into a phase angle?

Think about how many degrees in a circle and your frequency and now this time constant.

1/T=f. Thus frequency is 20Hz. how to find degrees in a circle?

You don't mean that question seriously, do you?
Sure you know how many degrees a full circle has?

Yes I am beginning to think this a wind up. How can someone who is obviously doing a course of some kind not have any notes with any examples of anything.
