Question

Find to the nearest tenth, the perimeter of triangle ABC if A=(2,6) B=(5,10) C=(0,13)

Answer 1

Graph the points

Answer 2

then calculate the units from each point

Answer 3

since there is 3 sides. Then add three sides.

Answer 4

the distance between two points (x1,y1) and (x2,y2) is given by
\[d = \sqrt{(x2-x1)^2 + (y2-y1)^2}\]

so you have to calculate AB, AC and BC and add them up

Answer 5

use distance formula to find the distance between two points

Answer 6

ok thanks!

Answer 7

any time :)
