A plane flying at an altitude of 5 mi travels on a path directly over a radar tower. a. Express the distance d θ (in miles) between the plane and the tower as a function of the angle θ in standard position from the tower to the plane. b. If d θ = 5 , what is the measure of the angle and where is the plane located relative to the tower? c. Can the value of θ be π ? Explain your answer in terms of the function d .
