Question

A plane is descending towards a runway in Chicago. The plane is flying at an altitude of 7 miles and is 190 miles from the runway, as measured from the ground. What angle will the plane's path make with the runway?

Answer 1

height = 7 miles, base dimension is 190 miles

to find the angle on the ground up to the plane

use arctan(7/190)

acrtan on a calculator is tan^-1

arctan(7/190) = 2.1099 degrees. Round off as necessary
