Well, kind of.... The Prime Meridian by definition is 0 degrees. The world is divided into two parts: zero through 180 West Longitude, and zero through 180 East Longitude. { The world is 360 degrees around; 180 plus 180 =360.} Half of 180 = 90, so 90 would be one quarter of the way around. 77 degrees west would be just under 1/4 of the way around so, yeah, its kind of close to the Prime Meridian, but not really close-close. {Compared to, say, 10 degrees west.} Got it? If not, contact the link below for the person who first answered this question and I'll try to help you understand.
Longitude !
Mexico City is 99.133333 degrees west of the Prime Meridian
It is neither. The prime meridian is 0 degrees longitude. All other meridians are measured from this. East or west to 180 degrees.
90 degrees west
Halfway between the Prime Meridian and 80 degrees west has to be pretty close to 40 degrees west, we'd say.

The coordinates of Lisbon are 38.7223° N, 9.1393° W. Which means that Lisbon is West of the Prime Meridian (the Prime Meridian is zero degrees of Longitude).
Longitudes west of the prime meridian are given either as "40 degrees W" or "-40 degrees", with degrees represented by the "o" degree symbol.
39 degrees north of the Equator, 77 degrees west of the prime meridian.
90 degrees
Everything from 1 degree 50 minutes east to 8 degrees 13 minutes west. But the Prime Meridian, at zero degrees, is defined as the location of the British Royal Observatory in Greenwich, England.
