A painting in an art gallery has height and is hung so that its lower edge is a distance
Chapter 4, Problem 58(choose chapter or problem)
A painting in an art gallery has height and is hung so that its lower edge is a distance above the eye of an observer (as in the figure). How far from the wall should the observer stand to get the best view? (In other words, where should the observer stand so as to maximize the angle subtended at his eye by the painting?)
