The points A,B, and C are in the coordinate system, B (1,2),C(4,3), A is concealed. A,B,C constitute a triangle?ê?what is the coordinates of A?(1)The distance from A to B is 2
(2) The distance from A to C is 3
it seems to me that the answer is E....but can not confirm....
say the coord of A be (x,y)
then (1) => (x-1)^2 + (y-2)^2 = 4....
and same type of equation for (2)....when I solve the two equations....
I get...3x + y = 7........and there are many points x,y that satisfy this equation.
