waaaaaahhhh
coordinates for A and B had like 6 marks...shushu since it was easyy 4 u can u plz xplain :/
ok so N was (2,-1) ok
then the radius was 6.5
u join AN and NB to form a triangle then if u draw a perpendicular line from N to AB then u will have the height which u find by pythagoras theorem it is found to be equal to 2.5
now to find co-ordinates of A, A is 6 units to the left of N there fore x= 2-6=-4
y=-1-2.5=-3.5
to find co-ordinates of B,
x= 2+6=8
y=same as A= -3.5
i hope u understood this, and i hope it cleared ur doubt best of luck!
