NCEES Power Afternoon Problems 505, 508,511

If you try to solve this without converting to phase voltage, KVL around the loop should get you the answer also.

I tried the KVL around the loop and didn't get 12.95KV

I took

VAB = ( 70 angle -20 ) * (11.18 angle 63.48) + (12500 angle 0) - (70 angle -140)*(11.18 angle 63.48)

Can anyone tell me what I did wrong?
