Pls help me answer number 3

NOTE: PLEASE ALWAYS USE 3 DECIMAL PLACES THROUGHOUT THE PROCESS. The other picture is the guide-sample.

Thank you

Please answer the following:
1. A balanced star connected load has an impedance of 6+ j8 ohms per phase
connected to a balanced 3-phase 200 volts per phase. Determine: a) current per
phase b) line currents c) power per phase d) total power e) reactive power per phase
f) total reactive power g)total apparent power
2. Three 40-ohm resistors are connected in star across 300 V, 3 phase supply. If one
of the resistors is disconnected, determine the line current.
3. Three identical impedances are connected in wye to a 3-phase supply of 200 V.
The line current is 45 A and the total power taken is 20 kW. What will be the
resistance of the load in each phase?
