The simple solution is to make a scale drawing and then measure it.
No math and it gives a good visual idea of the geometry.
For example, at one inch per foot, you plot a vertical line representing
the tower height. Then go out horizontally in inches equal to the number
of feet your guy anchors are from the tower. Connect the anchor points
to the tower at the appropriate heights and you have an accurate
representation of your tower.
To determine the turning radius under your guy wires, measure the
distance between the tower and the appropriate guy wire, remembering
your scale factor (of 1 inch = 1 ft) and you've got it. NO MATH.
If that scale doesn't fit on your paper, use something smaller,
like 1/2 inch = 1 ft to represent tall towers. Using graph or
quadrille paper makes it even easier.
