Question

Using trig to find side

Answer 1

We can relate angles and sides using trigonometric ratios.

In this case, we know So we can write:

`\begin{gathered} \sin (\angle E)=\frac{\text{Opposite}}{\text{Hypotenuse}}=(FG)/(EF) \\ \sin (46\degree)=(91)/(EF) \\ EF=(91)/(\sin (46\degree)) \\ EF\approx(91)/(0.719) \\ EF\approx126.5 \end{gathered}`

Answer: EF = 126.5 ft
