To solve for one guy wire: You have a right triangle with 30 feet acting as the base and 75 feet as the height. Use pythagorean theorem to solve for the hypotenuse. a ^{2} + b ^{2} = c ^{2}, with a = 30, b = 75 then, c = 80.8 Now this is only the length of one guy wire so you need to multiply this answer by three. 80.8 * 3 = 242.4 feet
