    Step-by-step explanation:

    The ladder forms a right angle triangle with the wall. The straight line distance from the bottom of the window to the ground forms the opposite side. The distance from the bottom of the ladder to the house represents the adjacent side. To determine the required length of the wire, c, we would Pythagorean theorem which us expressed as

    Hypotenuse² = opposite side² + adjacent side²

    Therefore,

    c² = 6² + 5² = 36 + 25 = 61

    c = √61 = 7.81 ft
