Can you solve the question step by step with clearly writing ?

Extracted text: 4. A single phase full wave fullycontrolled (means all switches are thyristors) bridge rectifieris connected to a resistive load of 140 ohm. Supply voltage is 400V and frequency is 50HZ. Determine the values of average and rms voltage, current and power transferred to the load for: a) α= 35 degre es b) α= 110 degre es c) Do you need a freewheeling diode forthis case. (Hint: See page 37 of the book Fewson)
