Am I right?
\sin(70) = 232.1 / x
234 - 1.9 = 232.1

Answer:

959.4m

Step-by-step explanation:

The diagram illustrating this problem is attached below:

The required length of the zipline is labeled x.

Using trigonometric ratios:


\cos \theta=\frac{\text{Adjacent Length}}{\text{Hypotenuse}}

Therefore:


\begin{gathered} \cos 76=(232.1)/(x) \\ x\cos 76\degree=232.1 \\ x=(232.1)/(\cos 76\degree) \\ x=959.4m \end{gathered}

Thus, 959.4 m of the line is needed.
