A circle with center at point O and ∠AOC = 160°.
Statement (1) : Angle x = 100° and angle y = 80°.
Statement (2) : The angle, which an arc of a circle subtends at the center of the circle is double the angle which it subtends at any point on the remaining part of the circumference.
Both statements are true.
