For maximum power transfer through a transmission line with equal voltage magnitudes at both ends, the phase angle difference between the voltages must be equal to the impedance angle of the line, i.e., $\tan\delta = x/r$. The question asks for a condition on $r$ and $x$ themselves.
The power is transmitted through a transmission line of impedance (r + jx) at equal voltage at both ends. The maximum power can be transferred under the steady-state condition if
