we can make a triangle

It is a right triangle, to fnd h we can use trigonmetric ratios, for example sine


\sin (\alpha)=(O)/(H)

where alpha is the reference angle, O the opposite side from the angle and H the hypotenuse

using 75° as reference angle we can replace


\sin (75)=(h)/(60)

and solve for h


\begin{gathered} h=60\sin (75) \\ h=15(\sqrt[]{6}+\sqrt[]{2})\approx58 \end{gathered}

maximum height is 58ft
