A) \[45{}^\circ \]
B) \[60{}^\circ \]
C) \[90{}^\circ \]
D) \[30{}^\circ \]
Correct Answer: A
Solution :
\[\tan 45{}^\circ =1\] \[\cot 45{}^\circ =1\] \[\therefore \,\,\,\,\,\,\,\,\,\tan 45{}^\circ +\cot 45{}^\circ =1+1=2\] \[\therefore \,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\theta =45{}^\circ \]
