In a mall, a shopper rides up an escalator between floors. At the top of the escalator, the shopper turns right and walks 11.72 m to a store. The magnitude of the shopper's displacement from the bottom of the escalator to the store is 16.0 m. The vertical distance between the floors is 5.18 m. At what angle is the escalator inclined above the horizontal?
