An airplane flies at an altitude of y = 7 miles toward a point directly over an observer (see figure).

Question

The speed of the plane is 700 miles per hour. Find the rates (in radians per hour) at which the angle of elevation 𝜃 is changing when the angle is 𝜃 = 30°, 𝜃 = 60°, and 𝜃 = 70°.

(a) 𝜃 = 30°

?

(b)𝜃 = 60°

?

(c)𝜃 = 70°
