The expressions for the steady-state voltage and current at the terminals of the circuit seen in are \[ \begin{array}{l} v_{g}=270 \cos \left(5000 \pi t+77^{\circ}\right) \mathrm{V}, \\ i_{g}=7 \sin \left(5000 \pi t+132^{\circ}\right) \mathrm{A} . \end{array} \] Part A What is the impedance seen by the source? Express your answer in ohms to three significant figures. Enter your answer using angle notation. Express argument in degrees.
