Odpowiedź i szczegółowe wyjaśnienie:
[tex]a)\ a=\sqrt2\ cm;\ b=\sqrt3\ [cm]\\\\a^2+b^2=c^2\\\\(\sqrt2)^2+(\sqrt3)^2=c^2\\\\c^2=2+3\\\\c^2=5\\\\c=\sqrt5\ [cm][/tex]
[tex]b)\ a=2\sqrt2\ [cm];\ b=4\sqrt5\ [cm]\\\\a^2+b^2=c^2\\\\(2\sqrt2)^2+(4\sqrt5)^2=c^2\\\\4\cdot2+16\cdot5=c^2\\\\8+80=c^2\\\\c^2=88\\\\c=\sqrt{88}=\sqrt{4\cdot22}=\2\sqrt{22}\ [cm][/tex]
