In same segment, if ∠ACB = 40°, find ∠ADB.
40°
Angles subtended by the same arc at the circumference, when the vertices lie in the same segment of a circle, are always equal.
In the given figure, points C and D lie in the same segment with respect to chord AB, so \(\angle ACB\) and \(\angle ADB\) are angles in the same segment.
By the angles-in-the-same-segment theorem, \(\angle ADB = \angle ACB = 40^\circ\).
