Dear Engineers
Please can anybody help me to solve this AC.voltage controller problem.

A single -phase 2300V(rms),60Hz source supplies a full-wave Ac Voltage controller.
The Conduction angle = d = 155" degrees. The controller power an Ac motor operationg at 0.75 power factor,lagging. The Average current through each thyristor is 600 A.
Find a. Find the delay angle alpha= a=?
b. Find the Equivalent resistance and Inductive reactance of the motor

thanks and best regards
