Question 30

A diagram showing a circle with center O. Points A and C are on the circumference. Lines AB and CB are tangents to the circle at points A and C respectively, meeting at point B outside the circle. The angle ABC is labeled as 46 degrees. Radii OA and OC are drawn from the center O to points A and C on the circumference.

A A\,A and C C\,C are points on the circumference of a circle, centre OOO. AB AB\,AB and BC BC\,BC are tangents to the circle.
