Source: INEP – proof and template of the 2nd day, Notebook 5 – Yellow.
The ENEM Mathematics and Technologies test 2025 was administered on the 2nd day and will from question 136 to 180. This post addresses questions 136 to 150. The numbering used here is that of the Notebook 5 – Yellow; us In other notebooks the same questions appear in a different order.

Due to frequent bicycle thefts, the city hall plans to allocate police officers in strategic positions to patrol this cycle path, in order to make it fully protected. A point on the cycle path is considered protected if there is at least one police officer at most 200 m away from that point, positioned over the cycle path. The figure illustrates a point $P$ on the cycle path, that will be protected if there is at least one police officer positioned over the dark gray region.
