Answer:
39.6 ft.
Step-by-step explanation:
Height of the top of the goal post would be x + 5.5
So for we need to calculate x first,
For x:
[tex]tan\ \theta = \frac{perpendicular}{base}\\\\tan\ 61=\frac{x}{20}\\\\20*tan61=x\\\\x=20*1.732\\\\x=34.64\ ft[/tex]
So height of the top of the goal post would be 34.64 + 5.5 which is
39.64 ft. rounding it to nearest tenth would be 39.6ft.
