Power System Analysis I

A 3-phase 132 kV, 50 Hz overhead line delivers 50 MVA and pf 0.8 lagging at its receiving end. The constant of the line are $A = 0.98\angle 3^\circ$ and $B = 110\angle 75^\circ,\Omega$ phase. Find (i) sending end voltage and power angle (ii) sending end active and reactive power (iii) line losses.
