if point C has coordinates 4 2 and point D has coordinates 8 5 then what is the length of CD class=

Respuesta :

[tex]Length = \sqrt{(Y_2-Y_1)^2 + (X_2-X_1)^2} [/tex]

[tex]Point \ (4, 2) \ and \ (8, 5)[/tex]

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

[tex]Length = \sqrt{(3)^2 + (4)^2} [/tex]

[tex]Length = \sqrt{9 + 16} [/tex]

[tex]Length = \sqrt{25} [/tex]

[tex]Length = 5[/tex]

[tex]\ Answer \Longrightarrow \boxed {\boxed {Length = 5}} [/tex]
