Question : AB and BC are two chords of a circle with centre O. Both chords are on either side of the centre O. Point A and point C are connected to the centre O, such that $\angle B A O=36^{\circ}$ and $\angle B C O=48^{\circ}$. What is the degree measure of the angle subtended by the minor arc AC at the centre O?
Option 1: 136°
Option 2: 144°
Option 3: 120°
Option 4: 168°
Correct Answer: 168°
Solution : In $\triangle$BOC, OB = OC (since they are radii) $\angle$OBC = $\angle$OCB = 48° $\angle$BOC = 180° – (48° + 48°) = 84° In $\triangle$AOB, OA = OB (since they are radii) $\angle$OAB = $\angle$OBA = 36° ⇒ $\angle$AOB = 180° – (36° + 36°)
