To find the height of Delicate Arch in Arches National Park in Utah, a surveyor levels a theodolite with the bottom of the arch. From there, she measures the angle of elevation to the top of the arch omegle (link, that didn't even work, removed)

She then measures the distance from where she stands to a point directly under the arch. Her results are shown in the diagram.

What is the height of the arch?

Going from 2714 to 1007, so down to 1707

3 degree descent, distance from plane to airport is

$$tan 3={O\over A}\\ A={O\over tan3}={1707\over tan3}=32571$$
