If you sight Polaris with an astrolabe and determine its altitude is 20° above the horizon, then what does this tell you about your position on the Earth?
nothingyou must know your location from a map
you must be 20° from the north pole
you must be 20° above (north) the equator
you must be 20° east or west of true north
