A) \[x+\sqrt{3}y=3\]
B) \[\sqrt{3}x+y=3\]
C) \[x+y=\sqrt{3}\]
D) None of these
Correct Answer: A
Solution :
\[(1+OB)\cos 30{}^\circ =2\sqrt{3}\] \[\Rightarrow \]\[1+OB+2\sqrt{3}\times \frac{2}{\sqrt{3}}=4\] \[\Rightarrow \] \[OB=3\] \[\Rightarrow \] \[B=(3,0)\]and \[m\]of \[BC=\tan 150{}^\circ =-\frac{1}{\sqrt{3}}\] So, the equation of\[BC\]is \[y-0=-\frac{1}{\sqrt{3}}(x-3)\] i.e., \[x+\sqrt{3}y=3\]You need to login to perform this action.
