Equation of director circle for this circle is
( x − 7 ) 2 + ( y + 1 ) 2 = 2 r 2 = 5 0
Putting ( 0 , 0 ) in the equation, we find that it lies on the director circle. Since, tangents drawn from any point on the director circle of a circle to the given circle are always perpendicular. So, the angle between the tangents will be 2 π .
