Step-by-step explanation:
The angle between them should be 120∘ because in that case the figure formed by the intersection point of pair of tangent, the two end ponits of those two radii ( at which tangent are drawn ) and the centre of the circles is a quadrilateral. Hence, the required angle between them is 120°
