The Deep Dive
To find the length of the wooden board, we can use trigonometry. Since the board forms a
angle with the ground, we can use the cosine function. Cosine of the angle is equal to the adjacent side (distance from the house) divided by the hypotenuse (length of the board):
Rearranging this gives us:
Using a calculator, we find that
. Thus:
So, the length of the wooden board is approximately 12.2 feet.
