Draw this
Pole is 14 m high
Peg is 15 m from pole
Those are two legs of a right triangle
the distance from the top squared is equal to the sum of the squares of 14 and 15. This is the sum of 196+225=421.
The distance to the top is therefore the square root of 421, or 20.52m. The first is exact, the second is rounded.
