Answer:
53.68 ft
Step-by-step explanation: Since ∠Q is 90°, ΔOPQ is a right triangle. So, there are hypotenuse, opposite side and adjacent side. And there the trigonometric relations: sine, cosine and tangent.
The image of the triangle is below.
Side
is opposite to the measure of ∠O and the length required is the adjacent side to the m∠O. According to the trigonometric relations:
Substituing:
Using a calculator, tan(5) = 0.0875:
The length of
to the nearest tenth of a foot is 53.68 feet.
