If the angle subtended by a chord at the center is 150°, what is the angle subtended at a point on the circle in the same segment?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. 75°
Angle at center = 2 × angle at circumference (same segment)
Angle at circumference = Angle at center / 2
Angle at circumference = 150 / 2
Angle at circumference = 75°
