Folded kite fabric — the kite-maker's crease angle

In her workshop, a kite-maker folds a rectangular sheet of kite fabric 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 fabric and the folded-over edge is 16°, and x is the angle between that folded edge and the crease. Find angle x.
