I know this is simple, but I need help. I've attached the image (of ISS and SS with angles, etc..) Based upon the information provided on International Space Station (I.S.S.) and Space Shuttle (S.S.), and tracking stations C and D, answer following questions: a) What are the altitudes of the space station and space shuttle? b) How far apart are they? (horizontal and vertical distances) c) How far is each space vehicle from each of the tracking stations?
