A 12-foot guy wire is to be attached to a tree at a 30 degree angle to the ground. At what height on the tree should the guy wire be attached? How far from the tree should the wire be attached to the ground?

  • geometry -

    a. We form a rt triangle:

    A = 30 Deg. = Angle between hyp. and
    hor. side.
    Y = Ht. of guy wire attached to tree.
    Z = hyp. = 12 Ft guy wire.

    Y = 12*sin30 = 6 Ft.

    b. X = 12*cos30 = 10.4 Ft.
