In a circle, the angle subtended by chord AB at a point on the circumference is 35°. What is the angle subtended by the same chord at the center of the circle?
Show answer & explanation
Correct answer: B
Explanation
Angle at the circumference = 35°
According to the formula:
Angle at the center = 2 × Angle at the circumference
Angle at the center = 2 × 35° = 70°
