In a balanced three-phase wye-delta system, the source has a positive ($abc$) phase sequence and a phase voltage of $\textbf{V}_{an} = 120 V_{rms} \angle 25^\circ$. If the line impedance is zero and the line current is $\textbf{I}_{aA} = 6 A_{rms} \angle 65^\circ$, find the load impedance per phase in the delta.
$\textbf{V}_{AB} =$ $V_{rms} \angle$ $^\circ$
$\textbf{I}_{AB} =$ $A_{rms} \angle$ $^\circ$
$\textbf{Z}_p =$ $\Omega \angle$ $^\circ$
