Two friends sit at points A and B on the edge of a circular fountain. The arc between them subtends 100° at the center. What is the angle subtended by arc AB at a point on the opposite side of the circle?
Show answer & explanation
Correct answer: C
Explanation
Given:
Angle subtended by arc AB at the center = 100°
Formula:
Angle subtended on the circle = Half the angle subtended at the center
Angle subtended on the circle = 100° / 2 = 50°
