If its a heading, they are opposite by 180 degrees. If its a strike (eg, a geometric plane), then they are the same.
The modern and clear way to say these things are:
N5E = 005 degrees (005°)
S5W = 185 degrees (185°)
Edit - the way to get the degree symbol ° is Alt 248.
The quadrant method to obtain a bearing is used only in the US, and then not even consistently; the international and SI standard for a bearing is 000° to 359° (as 360° = 000°).
Some examples:
North (N) = N0E = 000°
Northeast (NE) = N45E = 045°
East (E) = N90E = 090°
South (S) = S0W = 180°
Southwest (SW) = S45W = 225°
West (W) = S90W = 270°
To add to the confusion with the quadrant system, west (270°) could be called N90W or S90W. But by convention, the first direction (N or S) should be followed by the number of degrees in a clockwise direction, and then the direction of the "correction."
In mathematics, surveying, aviation, nautical navigation, and engineering the compass direction (or bearing) is always given as a three digit number (except for runways which omit the last digit) between 000 and 360. The only use of the quadrant system seems to be some geologists in the US, and that is gradually disappearing because it is difficult to use quadrants with GIS.
Hope that helps!

What happened did you sleep thru class or are you afraid to open your textbook? Draw the graph like your teacher told you to. There are 90 degrees in each quadrant. North is up, South is down, East is to the right, and West is to the left. Now if You start at North and go to the angle which is 5 degrees toward East or right and call that your starting point all you have to do is count the number of degrees it takes to get to the end point. So it's 85 degrees to the line pointing East plus 90 degrees to the line pointing South then another 5 degrees to the line S5W. You add the three numbers together. 85 + 90 + 5 = 180 degrees. You need to do your own homework if you want to learn. You need to learn, it's very important for your future.
Georock1959 is talking about something called azimuth bearing and it's always counted in degrees starting from the north. So West would actually be N275 degrees. It's always counted clockwise so S5W would be N185 degrees.

Normally, it is 180 degrees....but sometimes, especially in engineering survey work, this would mean 0, which means these two consecutive lines are on top of each other going in opposite directions. Of course, these lines would have a distance attached to them as well.
