Question

The diagram shows Earth represented by circle O, a satellite at point B, and tangent to circle O. AB is 21,800 mi. The radius of Earth is about 4,000 miles. What is the approximate distance from the satellite to the surface at point C? Explain.

Answer 1

A. 18,164 miles; is a tangent and are radii. Use the Pythagorean Theorem to find BO and subtract OC to find the distance the satellite is from the surface.
B. 22,164 miles; is a tangent and are radii. Use the point of tangency theorem to find the distance the satellite is from the surface.
C. 17,430 miles; is a tangent and are radii. Use the Pythagorean Theorem to find BO and subtract CB to find the distance the satellite is from the surface.

Answer 2

hey elizabeth, what course are you taking so I have a better idea which book to look up to do this problem. lol. is this trig precalculus?

Answer 3

it's common core geometry

Answer 4
