Lol do you have any idea how AMRAAM works?
First off, no AMRAAMs don't have a 180km range (at least nothing confirmed), and anything near the maximum range needs to be a highly lofted trajectory with basically zero kinematic performance once it reaches that range.
It would also take an AMRAAM around 2 minutes of flight time to reach a target at/beyond 150km.
This means you need a Ukrainian jet to be in the air, with an AMRAAM, have the Su-57 on radar track (either from the AMRAAM launch platform itself, or other sensor platforms like their SAAB AWACS) and be confident that the Su-57 isn't going to turn around in the next minute and a half.
There is a higher chance of the Su-57 being downed by friendly air defence than a Ukrainian-fired AMRAAM.
The only thing an AMRAAM is going to hit at 100+ miles is an AWACS, tanker, cargo plane, civillian airliner, or a fighter plane that has a pilot trying to commit suicide.
