Find the total power

Circuits (2) ;-
Va = Um Cos (wt)
ia = Im Cos (wt-d)
] Pa= Um Im Cos (wt) _ Cos (wt_d)
=
Vb - Um Cos (wt_128)
ib = Im Cos (wt-120-9)
vc = Um Cos (wt +120)
ic = Im Cos (wt +120-d)
Pb= Vm Im los (wt_120) Cos (wt-128-Q)
} Pe=u
2= Um Im Cos (wh +120) los (wt +120-Q)
(Power) P= Pa + Pb + Pc
