The photo below has the question. Thanks!!

4. Three heaters and a three-phase y-connected motor are connected to a y-connected source of
208 v line-to-line. Each heater draws 10A at unity power factor (pf 1), and each phase of
the motor draws 2 A at 0.85 power factor
a. Find the total line current
b. Find the total power consumed.
Determine the motor's inductive reactance per phase if the motor's R and X are
considered to be in series
C.
