An airplane rises vertically 1000 feet over a horizontal distance of 1 mile. What is the angle elevation of the airplane's path?
The angle of elevation is approximately
We need to start by putting everything in the same units.
The angle of elevation is measured by the horizontal, so the vertical rise will be opposite to the angle of elevation,
The proper trigonometric ratio to use will be tangent, knowing that opposite measures
Hopefully this helps!
