Mathematics
1 answer:
OverLord2011 [107]3 years ago

Answer:

Step-by-step explanation:

You just need the distance formula here.  It's very simple to follow:

d=\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2    }

which, for us, looks like this:

d=\sqrt{(13-4)^2+(19-7)^2} and

d=\sqrt{9^2+12^2} and

d=\sqrt{81+144} and

d=\sqrt{225} so

d = 15
