1. A vertical pole 24ft. high is to be braced securely by four wires attached 8ft. from the top. If the wires are fastened to stake in the level ground at the vertices of square with its center at the foot of the pole and sides 20ft. What should be the length of each wire?

2. Work problem 1, if the pole is one the side of the hill that slopes at an angle of 30 degree, and the guy wires are fastened to stakes at the vertices of a square 32ft. on a side. Assume two of sides are parallel to line up the slope of the hill.

1. #1. well, each wire is the hypotenuse of a right triangle, with legs 16 and 10√2

back later for #2.
