1 ostrosłup:
h² + 4² = 10²
h² = 10² - 4²
h² = 100 - 16
h² = 84
[tex]\sqrt{h^{2} }[/tex] = [tex]\sqrt{84}[/tex]
h = [tex]\sqrt{4 * 21}[/tex]
h= [tex]2\sqrt{21}[/tex]
2 ostrosłup:
h² + 5² = 13²
h² = 13² - 5²
h² = 169 - 25
h² = 144
[tex]\sqrt{h^{2} }[/tex] = [tex]\sqrt{144}[/tex]
h = 12
3 ostrosłup:
h² + 3² = 9²
h² = 9² - 3²
h² = 81 - 9
h² = 72
[tex]\sqrt{h^{2} }[/tex] = [tex]\sqrt{72}[/tex]
h = [tex]\sqrt{36 * 2}[/tex]
h = 6[tex]\sqrt{2}[/tex]
