Folded flag — the scout leader's crease angle

At a campsite, a scout leader folds a rectangular flag along a diagonal crease from its top-left corner to its bottom-right corner, as shown. At the bottom-right corner, the angle between the right-hand edge of the flag and the folded-over edge is 44°, and x is the angle between that folded edge and the crease. Find angle x.
