Answer:

10.8

Step-by-step explanation:

√(5-(-5))² + (8 -4)²

√10² + 4²

√100+16

√116 = 10.8
  • C(-5,4)
  • D(5,8)

[tex]\\ \sf\longmapsto CD=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

[tex]\\ \sf\longmapsto CD=\sqrt{(5+5)^2+(8-4)^2}[/tex]

[tex]\\ \sf\longmapsto CD=\sqrt{(10)^2+(4)^2}[/tex]

[tex]\\ \sf\longmapsto CD=\sqrt{100+16}[/tex]

[tex]\\ \sf\longmapsto CD=\sqrt{116}[/tex]

[tex]\\ \sf\longmapsto CD=10.4[/tex]
