if you followed the 70 degrees W line of longitude north to the north pole and then continued on the same line south, what line of longitude would you bee in?

The line of longitude that continues the line longitude 70 degrees W line past the north pole is the 110 degrees E line

Explanation:

The line of longitude which the 70 degrees W line continues as is the 110 degrees East as we move past the north pole because the the difference in degrees between the initial line of 70 degrees W and the line of longitude being followed after crossing the north pole will be 180° as we have past half the rotation of the globe, which is 360°

Therefore, the line of longitude, x, being followed is therefore;

70 - 0 + x degrees east = 180°

Which gives;

70 + x degrees east = 180° degrees east

x degrees east = (180° - 70°) degrees east = 110° degrees east

x degrees east = 110° degrees east

Therefore, the line of longitude that continues the line longitude 70 degrees W line past the north pole is the 110 degrees E line.
