The Solution:
Given the diagram below:
Considering right-angled triangle ABC,
we can apply the Trigonometrical Ratio as below:
Similarly, considering right-angled triangle ABD,
we can apply the Trigonometrical Ratio as below:
Now, putting eqn(1) into eqn(2), we get
Solving for x, we have
Therefore, the correct answer is 32.43 feet.
