Really need help with this one

Question

A plane flying at an altitude of 17,000 feet begins descending at a constant rate when the beginning of the runway is 60,000 feet from a point on the ground directly below the plane. Find the measure of the angle of descent (depression) to the nearest degree. Assume the airplane lands right at the beginning of the runway.

Answer 1

Draw and label a diagram.

Angle is depression is equal to angle of elevation from runway to plane.

tan θ = 17000 / 60000

Can you solve for θ and answer?
