Qual è il teorema di Pitagora e come viene utilizzato per calcolare la lunghezza di un lato in un triangolo rettangolo?

In the pentagon \( A B C D E \) angle \( A C B= \) angle \( A E D=90^{\circ} \). Triangle \( A C D \) is equilateral with side length 12 cm . \( D E=B C=6 \) a. Calculate \( A E \).

3] The dimensions of the base of a cuboid are \( \sqrt{3} \mathrm{~cm} \). and \( (\sqrt{3}-1) \mathrm{cm} \). an ts height equals \( (3+\sqrt{3}) \mathrm{cm} \). Calculate its volume. \( L L=\sqrt{3} \)
