Trigonometry

[Brenda Diehl]

Help :? I have no idea what I'm doing with this problem.
A guy wire (a type of support used for example, on radio antennas) is attached to the top of a 50 foot pole and stretched to a point that is d feet from the bottom of the pole. Express the angle of inclination as a function of d.
Any help would be greatly appreciated!

THANK YOU[/b]

Hello, Brenda!

Did you make a sketch?

A guy wire is attached to the top of a 50-foot pole
and stretched to a point that is \(\displaystyle d\) feet from the bottom of the pole.
Express the angle of inclination as a function of \(\displaystyle d\).

           d

Does this suggest any particular trig function?
