Question

The angle between a tangent to a circle and the radius drawn at the point of contact is(a) 60° (b) 30° (c) 45° (d) 90°

Answer 1

the answer is d 90.

Answer 2

the ans is 90digri.because the tangent tuched the circle just one point.and when the radius touched the poient it is equal with the normal at the same point. and we know tangent and normal crossed eatch other in 90 digri. so the ans is 90.
