Question

Please help me solve this using the distance formula!!

Answer 1

Answer:

51.5 m

Step-by-step explanation:

Plot the points B and C. Then substitute the points in the distance formula.

B(-35,-20)  

$\sf x_1= -35 \ ; \ y_1=-20$

C(-10,25)

$\sf x_2=-10 \ ; \ y_2 = 25$

        $\sf \boxed{\bf Distance = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}}$

                          $\sf = \sqrt{(-10-[-35])^2+(25-[-20])^2}\\\\=\sqrt{(-10+35)^2+(25+20)^2}\\\\=\sqrt{(25)^2+(45)^2}\\\\=\sqrt{625+2025}\\\\=\sqrt{2650}\\=51.5 \ m$
