Both of those longitudes are marked by the same meridian ... halfway around the
globe from the Prime Meridian.
The spherical Earth has 360° of total longitude, divided into 180° east of the Prime Meridian and 180° west of the Prime Meridian.So the highest value for longitude is 180° (this is nominally the International Date Line, and 180° E is the same meridian as 180° W).
The 180 degree line of longitude is called the 180th meridian or the antimieridian. This line is 180 degrees east or west of the Prime Meridian such that longitude at 180E and 180W is the same line. The International Date Line basically follows this line from the North and South poles..
180° is halfway around a circle or a sphere. Beginning at the Prime Meridian, you can travel EITHER east OR west, and after you have traveled 180 degrees, you'll arrive at the same line either way ... the meridian of 180° E and W longitude, which is halfway around the Earth in either direction from the Prime Meridian.
30 E = Finland150 W = Alaska
20° N, 180° W puts you in the North Pacific Ocean.

The International Dateline roughly follows the line of longitude that is both 180° E longitude and 180° W longitude, which passes through the western Pacific Ocean. The Dateline is shifted east or west in several locations to maintain a common date for associated countries or regions (Russia, US, New Zealand).
Latitude: 27.3 W and Longitude: 54.5 E
W 90° = E (anti-clockwise) 180° = W 360° = M
104W is a longitude line. Anything labelled as "E" or "W" is longitude.
E stands for east. Half of the longitude lines are east, the other half are w for west.
