Odpowiedź:
[tex]\huge\boxed{|CD| = 100}[/tex]
Szczegółowe wyjaśnienie:
[tex]C = (-19, 62) \ \ \rightarrow \ \ x_{C} = -19, \ y_{C} = 62\\\\D = (41, -19) \ \ \rightarrow \ \ x_{D} = 41, \ y_{D} = -19\\\\|CD| = \sqrt{{(x_{D}-x_C})^{2}+(y_{D}-y_{C})^{2}[/tex]
[tex]|CD| = \sqrt{(41-(-19)^{2}+(-18-62)^{2}} = \sqrt{60^{2}+(-80)^{2}} = \sqrt{3600+6400} =\\\\=\sqrt{10000} = \boxed{100}[/tex]
