Paulo is flying a kite as shown
in the right. Find the length of the kite string.

The length of the kite string is 50 ft
The string and the kite form a right triangle.
So, the length can be calculated using Pythagoras theorem as follows:
c^2 = 30^2 + 40^2
This gives
c^2 = 2500
Take the square roots
c = 50
Hence, the length of the kite string is 50 ft
