A) \[({{105}^{o}},{{15}^{o}})\]
B) \[({{45}^{o}},{{75}^{o}})\]
C) \[({{15}^{o}},{{105}^{o}})\]
D) \[({{75}^{o}},{{45}^{o}})\]
Correct Answer: A
Solution :
\[\frac{\sin A}{\sin B}=2+\sqrt{3}\] \[\frac{\sin \left( {{105}^{o}} \right)}{\sin \left( {{15}^{o}} \right)}=2+\sqrt{3}\] \[\frac{\cos {{15}^{o}}}{\sin {{15}^{o}}}=2+\sqrt{3}\]
