Marinada '25

[lang=hr] Patrik se izgubio u kvadratu duljina stranica $3$. Na sreču u svakom vrhu nalaze se mobilni tornjevi koje mu prate lokaciju. Jedan kaže da je Patrik udaljen za $\sqrt{2}$ dok druga dva kažu $\sqrt{5}$. Koliko pokazuje četvrti toranj? [/lang] [lang=en] Patrik got lost in a square with side length $3$. Fortunately, there are mobile towers at each corner that track his location. One says that Patrik is a distance of $\sqrt{2}$ away, while the other two say $\sqrt{5}$. What does the fourth tower indicate? [/lang]
