A kite is flying at a height of 75 metres from the ground level, attached to a string inclined at `60^@` to the horizontal. Find the length of the string to the nearest metre.

A kite is flying at a height of 60 m above the ground. The string attached to the kite is temporarily tied to a point on the ground. The inclination of the string with the ground is 60^@ . Find the length of the string, assuming that there is no slack in the string.
