Find the impedance and phase in polar form

I am trying to simplify the circuit, but the 3C capacitor is in the middle, can I use PI to T transformation here?

Yes, you can.

 

Once you convert capacitor into impedance, the impedance is a "resistor". So, now you have 5 resistors. Since you have only resistors, you can apply all the resistor rules and transformations.
