Alternating Current Real Power Reactive Power

"A three-phase transmission line is 200 km long. It has a total series impedance of ( 25 + j110) ? per phase and a total shunt admittance of . It delivers 180 MW at 275 kV and 0.8 power factor lagging to a load connected at the receiving end.
Using the medium model of the line, determine the voltage, current, real power, reactive power and power factor at the sending end of the line.
