Pls help me answer number 2

Note : pls always use 3 decimal places throughout the process. 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?
