If from any point P on the circle `x^2+y^2+2gx+2fy+c=0` tangents are drawn to the circle `x^2+y^2+2gx+2fy+csin^2alpha+(g^2+f^2)cos^2alpha=0` then angle between the tangents is

If from any point P on the circle x^(2)+y^(2)+2gx+2fy+c=0 tangents are drawn to the circle x^(2)+y^(2)+2gx+2fy+c sin^(2)alpha+(g^(2)+f^(2))cos^(2)alpha=0 then angle between the tangents is

If from any point P on the circle x^(2)+y^(2)+2gx+2fy+c=0, tangents are drawn to the circle x^(2)+y^(2)+2gx+2fy+c sin^(2)alpha+(g^(2)+f^(2))cos^(2)alpha=0 ,then the angle between the tangents is: (A) alpha (B) 2 alpha (C) (alpha)/(2) (D) (alpha)/(3)

If from any point P on the circle x^(2)+y^(2)+2gx+2fy+c=0, tangents are drawn to the circle x^(2)+y^(2)+2gx+2fy+c sin^(2)alpha+(g^(2)+f^(2))cos^(2)alpha=0, then find the angle between the tangents.

If two tangents are drawn from a point to the circle x^(2) + y^(2) =32 to the circle x^(2) + y^(2) = 16 , then the angle between the tangents is

Tangents are drawn from any point on circle x^(2)+y^(2)-4x=0 to the circle x^(2)+y^(2)-4x+2=0 then angle between tangents is:

If the circle x ^(2) + y^(2) + 2gx + 2fy+ c=0 touches X-axis, then
