The glide slope is the path a plane uses while it is landing on a runway. the glide slope usually makes a 3º angle with the ground. a plane is on the glide slope and is 1 mile (5280 feet) from touchdown. use the tangent ratio and a calculator to find ef (the altitude of the plane) to the nearest foot. the plane is feet high

To be able to find the altitude of the plane, we use one trigonometric function in this case the best function to use is the tangent. It is expressed as:

tan (theta) = opposite side length / adjacent side length
tan 3 = altitude of the plane / 5280 ft
altitude of the plane = 276.71 ft

Hope this answers the question. Have a nice day.
