she should find the length from where the tower begins to where the cable touches the ground, and use that number to be leg B, with the hight of the tower being constant and being leg A. then she uses the two numbers to find the hypotenuse of the new triangle. Repeat this with the other 3 cables and you have the answer! (Note: leg A's length will remain constant, but leg B's length will not because it is reliant on how far away the cables contact the ground in relation to the tower.)
