How do I straighten scanned pages in Adobe Acrobat DC?

The pages I just edited are skewed a little - I couldn't scan them myself because the place where I scan is closed for Covid, so a friend did it for me, and I didn't want to be too fussy. I rotated them 90 degrees, cropped them, removed the specks, put the single pages into one 42-page file, and posted it on the website. Some day, when this pandemic is over, I will scan it myself and be very, very careful to get it perfectly straight, and do the rest over again. If I had seen this page before it was all done, yes I would have tried deskewing it too, but when I have done that in photo programs - even very good ones - the type has always lost some quality, and it is probably more important to have it sharp and clear than completely straight.
