Log(n+2) = 1- Log(n-1)
Log(n+2) + Log(n-1) = 1
log((n+2)*n-1)) = log(10)
n^2 + n - 2 = 10
n^2 + n - 12 = 0
n = -4, n = 3
------
n = -4 --> log of negative number, NG

Length of the distance of platform attachment point to just one foot above the ground is .

The slide is the hypotenuse of a triangle, and the side opposite the 50 degree elevation angle (where is bottom point of the slide), is vertical. How HIGH the platform, .
