A balanced three-phase source supplies power to three loads:
Load 1: 24 kW at 0.8 pf lagging
Load 2: 10 kVA at 0.7 pf leading
Load 3: unknown
If the line voltage at the load is 208 V rms, the magnitude of the total complex power is 41.93 kVA, and the combined power factor at the load is 0.86 lagging, find the unknown load.
