Answer:
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.
