Applying the Pythygorean Theorem

The tallest building in the world is Burj Khalifa in Dubai, United Arab Emirates, at 2717 feet and 160 floors.The observation deck is 1450 feet above ground level. How far can a person standing on the observation deck see (with the aid of a telescope)? Use 3960 miles for the radius of Earth.

Re: Applying the Pythygorean Theorem

This is the LOH lighthouse problem again.  The diagram still works but now L is the height of the observation deck.
