Question

To approach the runway, a pilot of a small plane must begin a 10 descent starting from a height of 1983 feet above the ground. To the nearest tenth of a mile, how many miles from the runway is the airplane at the start of this approach

Answer 1

I assume you mean a 10 degree descent.

Can you sketch this problem?

Answer 2

also, the ground is parallel to the flight of the airplane before it starts descending, so we can use alternate interior angles to label the angle at the bottom right
