# Ethernet cez ulicu

Karol a Jozef sú vášniví hráči počítačových hier a býva v domoch, ktoré sú presne naproti sebe cez ulicu, takže si vidia navzájom do okien. Rozhodli sa, že si svoje počítače prepoja telefónnym káblom aby mohli hrať spoločne hry. Karol býva v prvom poschodí a jeho okno je vo výške 4,5 metra nad chodníkom. Jozef býva v treťom poschodí a okno má vo výške 10,1 metra.
Ulica je od domu k domu široká 10 metrov. Koľko metrov telefónneho kábla budú potrebovať pre toto spojenie?

Každý z nich si počíta, že bude mať počítač umiestnený v izbe asi 2 metre od okna.

Result

x =  15.5 m
