A) \[{{110}^{{}^\circ }}\]
B) \[{{120}^{{}^\circ }}\]
C) \[{{90}^{{}^\circ }}\]
D) \[{{40}^{{}^\circ }}\]
Correct Answer: B
Solution :
(b): Reflex angle \[XOZ={{360}^{{}^\circ }}-{{120}^{{}^\circ }}={{240}^{{}^\circ }}\] \[\therefore \]\[\angle XYZ\] = Angle at the circumference \[=\frac{240}{2}={{120}^{{}^\circ }}\]You need to login to perform this action.
