Answer :
We can relate angles and sides using trigonometric ratios.
In this case, we know So we can write:
[tex]\begin{gathered} \sin (\angle E)=\frac{\text{Opposite}}{\text{Hypotenuse}}=\frac{FG}{EF} \\ \sin (46\degree)=\frac{91}{EF} \\ EF=\frac{91}{\sin (46\degree)} \\ EF\approx\frac{91}{0.719} \\ EF\approx126.5 \end{gathered}[/tex]Answer: EF = 126.5 ft
