I would say it could possibly be 67
The ladder is the hypotenuse of a 45 45 90 triangle.
The legs of a 45 45 90 triangle = hypotenuse / sqroot (2)
15 / 1.414 = 10.608
(Incidentally it is the "bottom" of the ladder that is 10.608 feet from the wall. The "top" of the ladder is touching the wall. LOL)
4,4,4,5,5,5,6,6,7,8,8,8,9,10,10,10,10
It is the number 7.
