And I'm thinking its got 4 wires, the two side wires are at 30 feet and the high side ground is level, so that one is 30 feet out also. So three of four wires are known, but the fourth, downhill one, needs to be worked out, like in the sketch above, but ignoring the high side? I'm thinking that if the angle of the wire with respect to the mast is known, and the mast height is known, and the angle of the slope is measured, then some trigonometry should get a result, either telling us the length of the wire, or the length of the ground axis. But, being a scalene triangle, could present problems.... A scalene can be broken into two right-angle triangles, which might help some. Oh why didn't I pay more attention in math class!
