Could use help thank u

For the circuit shown below, what are the following? (160 V)sin(120nt) n 4.0 0 490 UF 0000 20 mH (a) the total impedance (in () 4.7 (b) the phase angle between the current and the emf (in rad) x rad (c) Write an expression for i(t). (Use the following as necessary: t. Assume i(t) is in amps and t is in seconds. Do not include units in your answer.) i( t ) =
