Question 842297
The question is slightly open-ended.  B could be above or below the x axis.


For AB:

{{{sqrt((y-0)^2+(3-2)^2)=sqrt(10)}}}
{{{sqrt(y^2+1)=sqrt(10)}}}
{{{y^2+1=10}}}
{{{y^2=9}}}
{{{highlight(y=-3)}}} OR {{{highlight(y=3)}}}
The point B is (3,-3)  OR  (3,3).


(6,3) is a possibility for point C.  Figure this through visual thinking or draw a graph to help, or do some coordinate geometric algebra using slopes and line equations.
