Question

ABC is an equilateral triangle. the coordinates of B and C are ( 3,0 ) and (-3,0) respectively. find the coordinates of vertex A. also find the area.

​

Answer 1

Step-by-step explanation:

As ABC is an equilateral triangle,

and BC= 6 so, AC= 6,

CO=3, So

AO=

AC

=

6

AO=

36−9

=

27

=3

So, here x=0 and

y=3
