Question

In the given figure, if O is the center of circle, determine angle APB​

Answer 1

Answer:

120°

Step-by-step explanation:

since O is the center, it means that OA = OB = radius

=> OAB = OBA = 30°

=> AOB = 120° (180-60-60)

=> any angle drawn from AB to the major segment = 60° (120/2)

=> APB = 120° (180-60) since if we draw any angle to the major segment from AB, it will form a cyclic quadrilateral with APN at the opposite side.
