A bird sitting on top of a stop sign notices a piece of food on the ground, 11 ft from the base of the stop sign. If the bird has to look down at a 39° angle of depression in order to see the piece of food, what is the approximate distance from the bird to the food? (Assume the stop sign is at a right angle to the
ground.)
