The answer above is correct. Here is a little more explanation.
The formula is a2 + b2 = c2
a = 5 meters
c = 10 meters
Rearrange the formula
b = square root of (100 - 25)
b = 8.66 meters

What should be the horizontal distance in feet for a ladder to the wall?
The best tip I've come to is that for every four feet of height you have to climb, move the base one foot away from the wall. Better still is to have someone foot the ladder, or to fasten the ladder with a rope, preferably near the top of the ladder to avoid the ladder sliding sideways.

A ladder is leaning against a wall if you were going to climb the ladder are you better off if there is no friction between the ladder and the wall or ladder and the floor?
No. if the floor is smooth you must have friction between the ladder and the floor, or the ladder would just slide away. Technically you could do without friction between wall and ladder, but even that can be helpful in preventing the ladder from going sideways.
