A triangle ABC is drawn on a coordinate plane . Find the length of the side BC.
Answer:
Option A. [tex]\sqrt{65}\ units[/tex]
Step-by-step explanation:
we know that
the formula to calculate the distance between two points is equal to
[tex]d=\sqrt{(y2-y1)^{2}+(x2-x1)^{2}}[/tex]
we have
Observing the graph
[tex]B(3,5)\\C(2,-3)[/tex]
substitute the values
[tex]BC=\sqrt{(-3-5)^{2}+(2-3)^{2}}[/tex]
[tex]BC=\sqrt{(-8)^{2}+(-1)^{2}}[/tex]
[tex]BC=\sqrt{64+1}[/tex]
[tex]BC=\sqrt{65}\ units[/tex]
