all of them please. I have been stuck on these for a few hours

11. Three 9Z–30° N in a delta connection and 5Z45° N in wye-connection have been connected to a 480V
system. Find the line current and the total power.
12. Consider two loads in parallel: Delta 27Z–25° N, wye 10Z-30° N have been connected to a 208V
system. Find the line currents and the power in each load.
13. Consider two loads in parallel: Delta 10Z–36.9° N, wye 5Z53.1° N have been connected to a 100 V
system. Find the line currents and the power in each load.
14. Two Delta loads with 202-60° N and 18445° N have been connected to a 150 V system. Find the
power consumed in each load.
