3. That night Oscar took a break and gazed up into the sky. He noticed that there are
many satellites that orbit the Earth. He began wondering about the distance some of
these satellites are from the Earth. Satellite A orbits closer to Earth than Satellite B. At
one point in their orbits, the distance from Satellite A to Satellite B is 21,185.5
kilometers. Their distances from each other and the center of the Earth form a triangle
as shown.
For all calculations, assume:
The radius of the Earth is 6371 kilometers.
All satellites have a circular orbit.
• All related measurements lie on the same plane.

•
a. Determine the distance Satellite B is from the Earth.
