Question 1895Navigation General70% to pass
A great circle crosses the equator at 173°E. It will also cross the equator at what other longitude?
AI Explanation
The correct answer is C) 7°W.
A great circle is the largest circle that can be drawn on the surface of a sphere, and it always crosses the equator at exactly two points that are 180 degrees apart in longitude. Since the given great circle crosses the equator at 173°E, the other point where it crosses the equator must be 180 degrees away, which is 7°W.
The other options are incorrect because:
A) 173°W is the same longitude as 173°E, which is already given.
B) 73°E is not 180 degrees away from 173°E.
D) 73°W is not 180 degrees away from 173°E.
