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?
a. We form a rt triangle:
A = 30 Deg. = Angle between hyp. and
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.
