Question

from the point A two tangents are drawn to the circle x^2+y^2=1.if the equation of chord of contact is 2x+2y-1=0 then find the coordinates of A

Answer 1

Answer:

mark as brainlist plz thnx

Answer 2

Answer:

Step-by-step explanation:

it should be outside of circle as two tangents are drawn

t=0 is chord of contact

let a be h,k

then chord of contact=

hx+yk-1=0

comparing with given

h=2 and k=2
