Since the ground already has an elevation of 15 degrees, the ladder needs to
be set at 60 degrees to reach a height of 10 ft.
In order for a ladder to reach a height of 10 feet, the ladder needs to be
placed at 75 degrees angle to the ground. This is when the ground has no
angle of elevation or when it flat.
Now, if the ground has an angle of elevation of 15 degrees , the degrees in
angle the ladder needs to be set can be solved as follows:
<h3>Angles in degree: </h3>
Therefore, the ladder needs to set at an angle of 60 degrees if the
elevation of the ground is already 15 degree. The elevation of the ground
will complement the angle in degrees required for the ladder to reach 10
feet.
