Given a balanced three$-$phase system, the source is wye$-$connected with the voltage $600$V$,$ the impedance of the line between the source and the load is j$1/$phase$,$ and the load is delta$-$connected with the impedance $12+$j$9$ ohm$/$per phase.

Draw both three$-$phase and per phase circuits

Calculate the voltage phasor at the load terminal with the phase angle

Calculate the complex power absorbed by the load and its angle

Just need to know how to solve this, no drawing necessary. The answers are $530$V at an angle of $22$ degrees, and $56\mathrm{.}2$ kVA at an angle of $36\mathrm{.}9$ degrees.
