**Quick question on 3 phase before my final!!**

## Homework Statement

In equations for 3 phase power there is an angle that is mentioned, but I don't know if this is the angle of the impedance or another angle. I am a little confused. The equations are below.

## Homework Equations

P=(VrmsIrms)cos([tex]\theta[/tex])

Q=(VrmsIrms)sin([tex]\theta[/tex])

Any help?
