A satellite, B is 17,000 miles from the horizon of Earth, Earth's radius is about 4,000 miles. Find the approximate distance the satellite is from the Earths surface.

I do not understand how to do these problems

1. If I understand you correctly the distance you seek is
d = sqrt(17000^2 - 4000^2) - 4000

2. Clearly, I did not understand you. But after reviewing the scenario, the answer is clearly
d = sqrt(17000^2 + 4000^2)-4000 = 13,464
