Interactive practice questions

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
