The light from a 19-inch-tall egg incubator casts a 13-inch shadow across a shelf. Use reciprocal functions and the Pythagorean Theorem as necessary to determine the distance from the top of the incubator light to the farthest part of the shadow. What is the angle at which the incubator light casts its shadow?
