You're not chicken are you?

Actually, I wanted to see if anyone besides me could
solve the problem - no one else has.

O.K., Cecil, I finally figured out what you want to do. You want
a zero ohm input impedance, just like a 1/4 wave open stub. In that
case, you're absolutely right, the 600 ohm line should be 43.387
degrees long. If you call the 100 ohm line, line 1, and the 600
ohm line, line 2, then the criterion for what you want is:
tan(Bl1)*tan(Bl2)= Z01/Z02. This behaves sort of like a backwards,
transmission-line, Helmholtz resonator. I still don't know where you
come up with the 90 degree stuff. It isn't necessary to explain the
phenomenon, but if it waters your lawn, go for it.

(P.S. Check my math. Bl2 = atan((Zo1/Zo2)/tan(10)) =
atan(.166667/.17633) = 43.387.)
