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.
There are 360 degrees in a complete circle or sphere but in all longitude measurements, the total of the degrees is expressed as 2 halves of 180 degrees each, moving East and West from the prime meridian. East is positive and West is negative. Latitude is designated as North and South but in 90 degree sectors.
