[lang=hr] Šest stranica unutar četverokuta $ABCD$ (dakle četverokut + dvije njegove dijagonale) imaju duljine $7, 13, 18, 27, 36$ i $41$. Ako je duljina od $AB$ jednaka $41$, kolika je onda duljina od $CD$? [/lang] [lang=en] Six segments inside quadrilateral $ABCD$ (i.e., the quadrilateral together with its two diagonals) have lengths $7, 13, 18, 27, 36$ and $41$. If the length of side $AB$ equals $41$, what is the length of side $CD$? [/lang]
