An airplane flies at an altitude of 5 miles toward a point directly over an observer. Consider θ and x as shown in the figure. Not drawn to scale (a) Write θ as a function of x. θ(x) = (b) The speed of the plane is 320 miles per hour. Find dθ/dt when x = 10 miles and x = 5 miles. (Round your answers to three decimal places. ) when x = 10 dθ dt = rad/h when x = 5 dθ dt = rad/h
