Same pattern as Folding angle — find x. New numbers, new story. Try each one on paper, then check the working below — or watch it drawn out, the same way the problem above is.
Question 1
During a busy dinner service, a waiter folds a rectangular paper napkin along a diagonal crease running 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 napkin and the folded-over edge is 24°, and x is the angle between that folded edge and the crease. Find angle x.
