The Eastern Empire managed to divert the Visigoths into Italy, thus shoving the problem onto the Western Empire, which responded to this threat by pulling troops from the Rhine frontier. This triggered a pattern of events much like the cycle of anarchy in the third century C.E., only this time, no Aurelian or Diocletian emerged to save the Empire.
Because latitude runs from the equator to one or the other of the poles, 90 degrees. That's one-fourth of a full circle around the globe. Longitude starts at Greenwich, Englanâ¦d and runs, to the west or to the east, to the International Date Line (in the Pacific Ocean), 180 degrees.
The primary unit in which longitude and latitude are given is degrees (Â°). There are 360Â° of longitude (180Â° E â 180Â° W) and 180Â° of latitude (90Â° N â 90Â° S). Each degree can be broken into 60 minutes (â). Each minute can be divided into 60 seconds (â). For finer accuracy, fractions of seconds given by a decimal point are used. A base-sixty notation is called a sexagesimal notation.
