Find the value of $f$f, correct to two decimal places.

A right-angled triangle with a 27-degree angle at its base is shown. The side opposite the 27-degree angle is labeled as "$f$f m" indicating a length in meters that is not specified. The side adjacent to the 27-degree angle is labeled "8 m," indicating a length of 8 meters. The hypotenuse, connecting the vertex of the 27-degree angle to the right angle, is not labeled. The right angle is indicated by a small square at the triangle's base
