straight-line distance of an airplane to a control tower is 36.2 km. If the angle of elevation from the tower to the plane is 4°, and the plane is 24 km south how much west of the tower is the plane?

Answer 1

Given that the plane is 24 km southward from the control tower,

√(36.2² - 24²) yields a distance of 27.1 km maximum with no westardly direction.

The 27.1 km distance is the maximum distance it could be from the control tower with 24 km

being the southward distance and 0 km west.
