3 (Dolce & Pompey) - A set of 4 parallel lines form three segments over a transversal line, measuring 5 cm, 6 cm and 9 cm, respectively. Determine the length of the segments that this specific set of parallel lines forms over another transversal line. Please note that the segment in between the first and fourth parallel line measures 60 cm
