A surveillance camera is placed at the edge of a circular campus. If it captures an angle of 30° across two points on the perimeter, what is the angle subtended at the center?
Show answer & explanation
Correct answer: B

Given:
Angle at the circumference = 30°
Formula:
Angle at the center = 2 × Angle at the circumference
Angle at the center = 2 × 30° = 60°
