A kite is flying at a height of $75 \ m$ 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 $60^{\circ}$. Find the length of the string, assuming that there is no slack in the string.

 

Answer:

 

The length of the string $=$ $i\sqrt{i}i$
