A telephone pole is secured with two cables. The first cable is attached to the top of the pole and makes an angle of 70° with the ground. The cable is secured to the ground 8 m from the bottom of the pole. The second cable is attached to the top of the pole and secured to the ground 3.5 times as far from the pole as the first cable is, on the same side of the pole. Determine the length of the second cable, to the nearest tenth of a metre.
