The characteristic solution follows from solving the characteristic equation,
so that
A guess for the particular solution may be
, but this is already contained within the characteristic solution. We require a set of linearly independent solutions, so we can look to
which has second derivative
Substituting into the ODE, you have
Therefore the particular solution is
Note that you could have made a more precise guess of
but, of course, any solution of the form
is already accounted for within 
.

Answer:
The angle between the building and the ladder 6.9°
Step-by-step explanation:
Given data
AB = 50 ft = length of the building
BC = 6 ft
= Angle between the ladder & building
From Δ ABC
6.9°
This is the angle between the building and the ladder.
