## Homework Statement

I have included the problems attached below. I have looked at a recent post and the equations made sense to me but I am very new to 3 phase systems basically know only what I have learned from trying to answer my questions. i feel my attempt is wrong from what I have seen online as total power equation in 3 phase system. I have included link. I am not sure which equation to use now I think mine is wrong.[/B]
