The average power P of an electrical circuit with alternating current is determined by the equation P= VI Cos , where V is the voltage, I is the current, and is the measure of the phase angle. A circuit has a voltage of 122 volts and a current of 0.62 amperes. If the circuit produces an average of 7.3 watts of power, find the measure of the phase angle.
