To find the longitude, you can use the formula: Longitude = GHA - LHA. In this case, GHA is 173° and LHA is 358°. So, Longitude = 173° - 358° = -185°. Since longitude values range from -180° to 180°, you can convert -185° to 175° (by adding 360°), indicating that the location is at 175° E longitude.
They're labeled E (or W) to show that they're (E)ast or (W)est of the prime meridian (which is the line of longitude passing through Greenwich Observatory near London). 15 degrees East and 15 degrees West are the same distance from the prime meridian, but in opposite directions.
