Narrative:
Just outside of the marker; we put the gear down and went to flaps 25 degrees and got a trailing edge flap disagreement message. We executed a go around and went to flaps 20 degrees for the missed approach. We wanted to execute the trailing edge flap disagreement checklist before landing to ensure a safe operation. We accepted minimum fuel into ZZZ because of the favorable WX and conditions; which did not leave us much time to work on our problem. The procedures and checklist were completed; and we landed with alternate flaps; in the flaps 20 degree position. We were unable to get any landing performance information for runway; for a flaps 20 degree condition. Because of our fuel state; we decided to execute the landing; which was normal.

Title: A B757-200 FLIGHT CREW EXPERIENCED TRAILING EDGE FLAP DISAGREEMENT ON APPROACH. THEY WENT AROUND; RAN THE PROCEDURE; AND LANDED WITH 20 DEGREES OF FLAP.
Narrative: JUST OUTSIDE OF THE MARKER; WE PUT THE GEAR DOWN AND WENT TO FLAPS 25 DEGS AND GOT A TRAILING EDGE FLAP DISAGREEMENT MESSAGE. WE EXECUTED A GAR AND WENT TO FLAPS 20 DEGS FOR THE MISSED APCH. WE WANTED TO EXECUTE THE TRAILING EDGE FLAP DISAGREEMENT CHKLIST BEFORE LNDG TO ENSURE A SAFE OP. WE ACCEPTED MINIMUM FUEL INTO ZZZ BECAUSE OF THE FAVORABLE WX AND CONDITIONS; WHICH DID NOT LEAVE US MUCH TIME TO WORK ON OUR PROB. THE PROCS AND CHKLIST WERE COMPLETED; AND WE LANDED WITH ALTERNATE FLAPS; IN THE FLAPS 20 DEG POS. WE WERE UNABLE TO GET ANY LNDG PERFORMANCE INFO FOR RWY; FOR A FLAPS 20 DEG CONDITION. BECAUSE OF OUR FUEL STATE; WE DECIDED TO EXECUTE THE LNDG; WHICH WAS NORMAL.
