Simply because it doesn't matter in either case.
-- Zero east or zero west puts you on the Prime Meridian either way.
(Beginning on the Prime Meridian, you may travel 0° east or 0° west,
as you prefer, and you arrive at the same place either way.)
-- 180° is half-way around any sphere. Regardless of which direction you decide
to travel from the Prime Meridian, 180° east or 180° west puts you exactly half-
way around the Earth, in the same place.
For the same reason that your lawn is not above or below ground,or something like that.Zero and 180 degrees longitude form the boundary between east and west,so they are both, and they are neither.
180 degrees is both east and west longitude. It doesn't matter which way you gofrom the Prime Meridian ... if you go 180 degrees, you arrive at the same longitude.
Because it is where east and west are measured from. Sort of like zero is neither positive nor negative.:)
The degree of longitude east of 5 degrees west is 4 degrees west longitude.
Longitude lines measure how far (in degrees) you are East or West of the Prime Meridian (which is a longitude line that runs through Greenwich, England and is designated as 0° longitude).
The 60 degrees east line of longitude runs through the Ural Mountains.
There are 180 degrees of latitude between 45 and 40 degrees east longitude. However, if you meant how many degrees of longitude are there, there are 5 degrees of longitude between 45 and 40 degrees east longitude.
80 degrees east longitude
126 degrees on the East Longitude.
No point in Pennsylvania is at 78 degrees east longitude.
The latitude of that point is 30 degrees south, and its longitude is 90 degrees east.
Its latitude is going to be 60 degrees north, and its longitude will be 24 degrees east.
