A question about this circuit

[magodiafano]

I have a question about the circuit in the image:

**broken link removed**

I know that the Generator 1 is carrying 500 MW of active power and 50 MVar of reative. The voltages magnitudes (linetoline) are 500 Kv at both buses. At bus 1 (gen.1) Van as magnitude 500/sqrt(3) while phase is 0 KV.
Besides Ia = 1000000 and phase -5.71
I need to find the phase difference between Va'n' and theper phase reactance of the line (R=0).
How could I answer to these two questions?

is someone that could help me??
