A) \[{{75}^{{}^\circ }}\]
B) \[{{35}^{{}^\circ }}\]
C) \[{{65}^{{}^\circ }}\]
D) \[{{45}^{{}^\circ }}\]
Correct Answer: C
Solution :
(c): \[\angle BAO={{180}^{{}^\circ }}-({{70}^{{}^\circ }}+{{25}^{{}^\circ }})={{85}^{{}^\circ }}\] Also, \[\angle AOB={{180}^{{}^\circ }}-({{85}^{{}^\circ }}+{{30}^{{}^\circ }})={{65}^{{}^\circ }}\]You need to login to perform this action.
