If the equation of tangent to the circle and parallel to is , then the values of are
Step 1: Solve for the center and radius of the circle
Given equation of circle is
For the general equation of the circle is the radius is and the center is
Now comparing with the general equation of the circle we have
and
Therefore radius of the circle is
The center is
Step 2: Solve for the value of
We know that the distance of the point from the straight line is
Therefore the distance of the point from the tangent is the radius of the circle
Hence, Option (A) is correct i.e.
