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.

![]() SOH CAH TOA Sin = Opposite over Hypotenuse Cos = Adjacent over Hypotenuse Tan = Opposite over Adjacent Some People Have (sin = perpendicular/hypotenuse) Curly Black Hair (cosine = base/hypotenuse) Though Painted Brown (tangent = perpendicular/base) I've never forgotten it. Ian. -- |

Ian. Another great way to remember it.. It was beat into me by a Jr High Teacher, and I've just never forgotten it this way... The Indian Chief SohCahToa... 73 de AI8W, Chris |
