We apply the trigonometric ratio in finding the length of the guy wire,
The guy wire is the longest side of the triangle - the hypotenuse
Let the length of the guy wire be X ft
[tex]\begin{gathered} \cos 48^0=\frac{\text{Adjacent}}{\text{Hypotenuse}}=\frac{20}{X} \\ 0.6691=\frac{20}{X} \\ X=\frac{20}{0.6691}=29.89\text{ft} \end{gathered}[/tex]
Therefore, the length of the guy wire is 30 feet to the nearest foot
