I have a sloper that is 73 feet long.
The high end is 34 feet high, and the low end is 8 feet high.
What angle is the antenna?

It's a shame I can't figure out something I should have learned
in the 6th grade; but I don't know how to set the problem up.

Thanks,
Zack




SOH CAH TOA

Sin = Opposite over Hypotenuse
Cos = Adjacent over Hypotenuse
Tan = Opposite over Adjacent

34-8=26

So the Opposite is 26
the Hypotenuse is 73
Sin(theta) = 26/73 = 0.35616438356164383561643835616438

So Theta = ArcSin(0.35616438356164383561643835616438) =
20.864823641018812055586761532415 degrees

Or somewhere close to 21 degrees, if you're into rounding.

Some People Have (sin = perpendicular/hypotenuse)
Curly Black Hair (cosine = base/hypotenuse)
Though Painted Brown (tangent = perpendicular/base)
I've never forgotten it.

Another great way to remember it..

It was beat into me by a Jr High Teacher, and I've just never forgotten
