A 50 Hz, 275 kV line of length 400 km has the following parameters:
Resistance, R = 0.035 $$\Omega$$/km;
Inductance, L = 1 mH/km;
Capacitance, C = 0.01 $$\mu$$F/km;
The line is represented by the nominal-$$\pi$$ model. With the magnitudes of the sending end and the receiving end voltages of the line (denoted by $$V_S$$ and $$V_R$$, respectively) maintained at 275 kV, the phase angle difference ($$\theta$$) between $$V_S$$ and $$V_R$$ required for maximum possible active power to be delivered to the receiving end, in degree is ___________ (Round off to 2 decimal places).

In the figure, the voltages are
$${v_1}\left( t \right) = 100\cos \left( {\omega t} \right)$$
$${v_2}\left( t \right) = 100\cos \left( {\omega t + {\pi \over {18}}} \right)$$
and $${v_3}\left( t \right) = 100\cos \left( {\omega t + {\pi \over {36}}} \right)$$.
The circuit is in sinusoidal steady state, and R << $${\omega L}$$.
P1, P2 and P3 are the average power outputs. Which one of the following statements is true?
