A suspension bridge is being built. The top of the concrete tower is 35.5 metres above the bridge and the connection point for the main cable is 65.9 metres from the tower.

Assume that the concrete tower and the bridge are perpendicular to each other.

If the length of the cable is h metres, find h to two decimal places.
Please directly answer the question and provide the final value, e.g., 1, 2.5, 300.
