Použijte Pythagorovu větu, abyste vypočítal strany AB a BC.

Milý kolego, má-li být na 1. radku Pythagorova věta, doplňte si 2. mocnínu přepony.

Dobrý den, dovolím si i ještě ted poslat řešení, jelikož nevím, zda tazatel není žákem základní nebo méně pokročilým na střední skole. Nepodekoval, což chápu, ani já - 58 letá učitelka výpočet úplně nechápu ( palec nahoru jsem dala 1. odpovědi za chybějící umocněni úhlopříčky ). Dál nemám co dodat.
