Understand ac power concepts, their relationships to one another, and how to calcuate them in a circuit

For each of the following sets of voltage and current, calculate the
real and reactive power in the line between networks A and B in the
circuit shown. In each case, state whether the power flow is from A to B
or vice versa. Also state whether magnetizing vars are being transferred
from A to B or vice versa.

v=100 cos (ωt−45°) V;i=20 cos (ωt+165°) A.
