Odpowiedź:
a)
[tex]a^2 = 4^2 + 6^2\\a^2 = 16 + 36\\a^2 = 52 | \sqrt{}\\a = \sqrt{52}\\a = 2\sqrt{13}[/tex] ≈ 7,2[m]
b)
[tex]a^2 + b^2 = c^2 | - a^2\\b^2 = c^2 - a^2\\b^2 = 3^2 - 2,5^2\\b^2 = 9 - 6,25\\b^2 = 2,75 |\sqrt{}\\\\b=\sqrt{2,75} [m][/tex]≈ 1,7m
c)
[tex]c^2 = 0,2^2 + 0,3^2\\c^2 = 0,04 +0,09\\c^2 = 0,13 |\sqrt{}\\c = \sqrt{0,13}[m][/tex]≈ 0,4m
