A Trigonometric problem
Imagine a right angled triangle
The 25ft ladder is the hypotenuse
The wall of the house is the opposite side
The base is the adjacent side.
The angle 32 degrees
Using Sin = Opposite/Hypotenuse
Sin 32 = Opposite/25
Opposite = Sin32 * 25 = 13.3 ft
This is how far up the wall it rests on.
Then we use Cos = adjacent/hypotenuse
Cos 32 = adjacent/25
Adjacent = Cos 32 * 25 = 21.2 feet
This is distance between ladder and wall
on the ground.
Hope this helps
:-)
