A satellite B is 17000 miles from the horizon of the Earth E
A satellite, B, is 17,000 miles from the horizon of the Earth. Earth\'s radius is about 4,000 miles. Find the approximate distance the satellite is from the earths surface.
 Solution
The lenght of BC
= BO-CO
= sqrt( AB^2 + AO^2) -CO
= sqrt( 17000^2 +4000^2) - 4000
= 13463.25km
