5" random orbital will take care most of that corner. Scrape out the rest, it only needs a little more to go. If not, get one of those cheap Ryobi triangular sanders to take care of the corner. It wouldn't get your floor completely flat so you may have to fudge it a bit but that is such tiny corner that it should be noticeable.
