I'm stumped by this problem.(adsbygoogle = window.adsbygoogle || []).push({});

There's no symmetry in the circuit, so I can't ignore the 1 ohm resistor that bisects the triangle. Is there something else I'm missing? I'm supposed to show the Rab = 27/17 ohms.

Please see the attached diagram.

Thanks.
