Tentukan jarak antara dua titik dari pasangan titik berikut a. (10, 20), (13, 16) b. (15, 37), (42, 73) c. (-19,-16), (-2, 14)

a.
[tex] = \sqrt{ {(13 - 10)}^{2} + {(16 - 20)}^{2} } [/tex]
[tex] = \sqrt{9 + 16} [/tex]
[tex] = 25[/tex]

b.
[tex] = \sqrt{ {(42 - 15)}^{2} + {(73 - 37)}^{2} } [/tex]
[tex] = \sqrt{ {27 }^{2} + {36}^{2} } [/tex]
[tex] = \sqrt{2025} [/tex]
[tex] = 45[/tex]
c.

[tex] = \sqrt{ { ( - 2 - ( - 19))}^{2} + {(14 - ( - 16))}^{2} } [/tex]

[tex] = \sqrt{ {17}^{2} + {30}^{2} } [/tex]
[tex] = \sqrt{1189} [/tex]
[tex] = 34 .48[/tex]
