To approach the runway a plane must travel at a 7 degree decent starting from 2 miles above the ground, to the nearest mile how far away will the plane have to start its decent

Respuesta :

tan 7 degrees = 2 miles / distance from airport
distance from airport = 2 miles / tan 7 degrees
distance from airport = 2 miles / .12278
distance from airport = 16.3 miles
