A pole 11 feet tall is used to support a guy wire for a tower, which runs from the tower to a metal stake in the ground. After p

The given question is on trigonometry which requires the application of required <em>function</em> so as to determine the <em>value known</em>. So that the <u>length</u> of the guy wire is 67.0 feet.

<em>Trigonometry </em>is an aspect of mathematics that requires the application of some <u>functions</u> to determine the <em>value</em> of an unknown quantity.

Let the <u>length</u> of the guy wire be represented by l, and the angle that the guy wire makes with the <u>stake</u> be θ. So that applying the appropriate trigonometric function to determine the <em>value</em> of θ, we have:

Tan θ = \frac{opposite}{adjacent}

          = \frac{11}{4}

Tan θ = 2.75

θ = Tan^{-1} 2.75

  = 70.0169

θ = 70^{o}

Considering triangle formed by the <u>tower</u> and the <u>stake</u> to determine the value of l, we have;

Cos θ = \frac{adjacent}{hypotenuse}

Cos 70^{o}  = \frac{23}{l}

l = \frac{23}{Cos 70^{o} }

 = \frac{23}{0.3420}

l = 67.2515

l = 67 feet

The <u>length</u> of the guy wire is 67 feet.
