I must assume that you're not talking about any of the cities/towns of Angola in Indiana, Kansas, Louisiana, North Carolina, or New York, since the Prime Meridian doesn't come anywhere near North America. The point in the African country of Angola that's closest to the Prime Meridian is the point on the Atlantic coast at the west end of the Angola/Namibia boundary. The longitude at that point is 11.756° East ... about 710 miles east of the PM.
