Question

if the angle between two tangent of a circle which is 70° then angle between their radii is​

Answer 1

Answer:

40°

Step-by-step explanation:

Since tangents and radii are perpendicular at the point of contact, in the quadrilateral formed by the two radii and the tangents at their ends, we have two right angles at the two points of contacts.

Let the angle between the tangents be xo. Then

140+90+90+x=360⇒x=40o.
