Let's draw the diagram:
Since we need to calcula AX (hypotenuse) we can use the cosine function:
[tex]\begin{gathered} \cos (\theta)=\frac{adjacent}{hypotenuse} \\ \cos (30)=\frac{125}{AX} \end{gathered}[/tex]
Solve for AX:
[tex]\begin{gathered} AX=\frac{125}{\cos (30)} \\ AX\approx144.34ft \end{gathered}[/tex]
