Solution

90°
We have to find AOC.

As we know that the angle subtended by an arc of a circle at the centre is double the angle subtended by it at any point on the remaining part of the circle.

`angleAOC = 2 angleABC`

           `= 2 xx 45`

            = 90°

  Is there an error in this question or solution?
