Answer:

rida22 this is the third of these you asked for...

do you need help on the steps???

the solution is using the Pythagorean    theorem (a^2 + b^2 = c^2)

so distance "A" = x1-x2 which is 4 - (-4) in your problem = 8

[tex]a^2 + b^2 = c^2[/tex]

[tex]8^2 + b^2 = c^2[/tex]

"B" = y1-y2 = -5 - 2 = -7

[tex]8^2 + (-7)^2 = c^2[/tex]

64 + 49 = c^2

c^2 = 113

c = [tex]\sqrt{113}[/tex]
