A woman stands on a flat ground surface at the base of a 90 ft90\(\text{ ft}\) tall observation tower. A hawk takes off from the top of the tower, descending at an angle of 45∘45^{\(\circ\)} below the horizontal.

Determine the rate at which the angle of elevation θθ is changing with respect to the height of the hawk when it is located 65 ft65\(\text{ ft}\) above the ground.
