Answer:


\begin{gathered} DF=2.99\approx3.0\text{ ft} \\ <p><strong>Step-by-step explanation:</strong></p><p>To determine the length of DF, we can use the Pythagorean theorem, which is defined by the following diagram and formula:</p><p>Then, for DF:</p>[tex]\begin{gathered} 5^2+DF^2=5.83^2 \\ DF^2=5.83^2-5^2 \\ DF=\sqrt[]{5.83^2-5^2} \\ DF=2.99\approx3.0\text{ ft} \end{gathered}

Now, to find the angles So, for angle
\begin{gathered} \cos (E)=(5)/(5.83) \\ Finally, for angle [tex]\begin{gathered} \text{sin(F)}=(5)/(5.83) \\ F=\sin ^(-1)((5)/(5.83)) \\ F=\text{ 59\degree} \end{gathered}
