For an airplane during landing, an angle of approach is defined as the angle formed by the runway and the path of the aircraft as it approaches the runway. For a safe landing, pilots need to land the plane with an angle of approach between 2.7 and 4.0 degrees. Upon arrival at its destination, an airplane is at an elevation of 100 feet and is directly above a spot on the ground that is 1,450 feet away from the start of the runway. Use inverse trigonometry to describe the approach angle.
a) The approach angle is too large so it is unsafe to land.
b) approach angle is between 2.7 and 4.0 degrees so it is safe to land.
c) The approach angle is too small so it is unsafe to land.
