313,287 angle - 50,3 degrees ohms.

#### Explanation:

The total impedance of an ac series circuit is the phasor sum of the impedances of all the components in the circuit.

Applying the appropriate reactance formulae for magnitudes, as well as the correct phase angles, we get the answer as in the sketch :

Note this circuit is capacitive overall (current leads voltage) so has a leading power factor.
