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.)
sin 39° = 0.63
cos 39° = 0.78
tan 39° = 0.81
A. 8.58 ft
C. 14.10 ft
B. 13.58 ft
D. 17.46 ft
