1.I made Big Circles whose radius is the Line length + 5miles.
2.I made Small Circles whose radius is the 6miles at each Line Edges.
3.I made the Crescents that are cut the Big Circles from the Small Circles.
4.I got centroids from the Crescents.
5.I made new lines the centroids.
6.I obtained the line with overlapping Big Circles and the New lines.

I couldn't figure out the complete solution using just the Spatial Tools so I had to peek at the solution.  However, instead of just applying the same logic as the known solution, I used Spatial Tools to calculate the initial line lengths and direction in degrees, and calculated the extensions mathematically.

This was a tough one.  I ended up finding the bearing of the distance between start and end point of the original line. I  then created a trade area of the distance specified (default 5) around both the start and end point, split the trade area into points, then found the point on the opposite end of the trade area that matched the distance and bearing of both the start and end points.  Finally, I created a new line with the newly calculated start, end points.  I'm sure there was an easier way to do this, maybe with geometry formulas, but this seemed to work .
