Zadanie 5
a) [tex]1^{2}+2^{2}=x^{2} \\1+4=x^{2} \\x^{2} =5 \\x=\sqrt{5}cm\\[/tex]
b) [tex]2^{2}+1,5^{2} =x^{2} \\x^{2} =4+2,25\\x^{2} =6,25 \\x=2,5cm[/tex]
c) [tex]0,5^{2} +3,5^{2} =x^{2} \\x^{2} =0,25+12,25\\x^{2} =12,5\\x=25\sqrt{2} mm[/tex]
Zadanie 6
a) [tex]x^{2} =2^{2} +3^{2} \\x^{2} =13\\x=\sqrt{13}cm[/tex]
b) [tex]x^{2} =0,5^{2} +3^{2} \\x^{2} =0,25+9\\x^{2} =9,25\\x=5\sqrt{37}mm[/tex]
c) [tex]x^{2} =3^{2} +3^{2} \\x^{2} =18\\x=3\sqrt{2} cm[/tex]
