The question is followed by two statements I and II.
There is a circle with centre C at the origin and radius r cm. Two tangents are drawn from an external point D at a distance d cm from the centre. What are the angles between each tangent and the X-axis.
If (I) is given then angle of both of them
But with only (II) we cannot conclude two angles But we can say one of the angle is 90 degree(x axis bisectects one of the tangent) , but another cannot say.
So,Ans is A)
