In a circle, chord AB subtends an angle of 80° at the center. What is the measure of the angle subtended by the same chord at any point C on the circumference, on the same side as the arc?
Show answer & explanation
Correct answer: C
Explanation
Chord AB subtends an angle of 80° at the center.
The angle subtended at the circumference is half the angle subtended at the center.
Angle = 80° / 2 = 40°
