Homework Help: Height of tree Homework problem

  1. Sep 26, 2006 #1
    Suppose there is a tree of unknown height. I am standing 76 meters away from the tree and the top of the tree is 32 degrees from where I am standing. Could I find the height of the tree by this:

    76 cos(32) =64
    76 sin(32) =40

    Magnitude = SQRT 64^2 + 40^2
    Height of Tree equals 75 meters??

    I may be wrong, but:

    Opposite = adjacent * Tan angle
    = 76 * Tan 32
    = 47.5

    Is that one of your answers? If not, forget I replied. :D

    I think that is the right way. I think 47 meters is the correct answer.
