A) \[\text{90 }\!\!{}^\circ\!\!\text{ }\]
B) \[\text{44 }\!\!{}^\circ\!\!\text{ }\]
C) \[\text{224 }\!\!{}^\circ\!\!\text{ }\]
D) \[\text{134 }\!\!{}^\circ\!\!\text{ }\]
Correct Answer: B
Solution :
According to the given figure \[\angle \text{AOC = 90 }\!\!{}^\circ\!\!\text{ , }\angle \text{BOC =134 }\!\!{}^\circ\!\!\text{ and}\] \[\angle AOB=\angle BOC-\angle AOC\]\[\text{=134 }\!\!{}^\circ\!\!\text{ -90 }\!\!{}^\circ\!\!\text{ =44 }\!\!{}^\circ\!\!\text{ }\]
