A granular substance such as sand naturally settles
into a cone-shaped pile when poured from a small aperture. Its height depends on the humidity and
adhesion between granules. The angle of elevation of a pile, q, is
called the angle of repose. If the height of a pile of sand is 13 feet and its diameter is
approximately 43 feet, determine the angle of repose. Round answer to nearest degree.
