The angle between two tangents drawn from an external point to a circle is 60°. What is the angle subtended by the chord connecting their points of contact at the center?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 120°.
The angle between the two tangents is supplementary to the angle subtended by the chord joining the points of contact at the center.
Angle between tangents = 60°
Angle at center = 180° – 60° = 120°
