Someone already did this problem but with the wrong values that weren't give? How can I get a question back when they were completely wrong? But need help.

Draw the complete 3-phase circuit, in the phasor domain, noting the unknown load 2 as Zin each
phase. Redraw just the a-phase of the circuit and calculate impedance of load 2 based on the
ihformetion provided, the velitage aeross the loads (VAN) and the current through the a-phase. What is
the total complex power supplied by the source? If the source frequency is 60 Hz, what component
values should be used for the 2 loads?

Circuit Description:
Assume you have a balanced 3-phase system. The sources have an abc sequence and are Y-connected.
V an=120Z 20°VRMS. There is no internal source impedance or line impedance. The source feeds 2
Y-connected loads in parallel. The impedance of load 1 is 4+ j 3 2/4. The complex power for the a-
phase of load 2 is 300 36 °VA.
