could u find the co-ordinates of A and C ?

hartnn · Answer

@Carol329 what are the co-ordinates of A and C ?
do u know the distance formula ?

anonymous · Answer

nopee :(

hartnn · Answer

ok, how much is a far from the origin (0,0) in x direction and y-direction ?

hartnn · Answer

Carol, the co-ordinates of A are (-1,3)
can u make out how ?

anonymous · Answer

and c is -2,2 lol i didnt kno thats what you were asking

hartnn · Answer

close
C is (2,-2)
because its on left ---> x coordinate  positive
its down , y co-ordinate negative.
ok?

hartnn · Answer

now using distance formula:
d= $\sqrt{(x_1-x_2)^2+(y_1-y_2)^2}$
we get distance as
d=$\sqrt{(2-(-1))^2+(-2-3)^2}$ = ??
can u solve further ?
