FSMN - Прямоугольник. Проведены диагонали SN и FM. O - точка пересечения. Из точки O к стороне FN проведена средняя линия OK. OK = 24 SF = ?

OK = 24, FN = ? To find FN, we need additional information such as the length of SK or the relationship between OK and SK. Without this information, it is not possible to determine the value of FN.
