Question
In a cyclic quadrilateral ABCD, the diagonals AC and BD
intersect at E. If ∠AEC = 120° and ∠BED = 30°, what is the measure of ∠ADB?ÂSolution
Since ABCD is a cyclic quadrilateral, opposite angles sum up to 180°. Also, in cyclic quadrilaterals, ∠AEC + ∠ADB = 180° by the property of intersecting chords. Thus, ∠ADB = 180° - 120° = 60°. Correct answer: c) 60°
