    The value of sin\[\theta \] in the adjoining figure is

    A)  \[\frac{12}{5}\]                        

    B)  \[\frac{12}{13}\]

    C)  \[\frac{13}{12}\]                                  

    D)  \[\frac{5}{12}\]

    Correct Answer: B

    Solution :

    (b) \[AB=14-9=5\] \[BC=12;AC=\sqrt{{{5}^{2}}+{{12}^{2}}}=13\Rightarrow sin\theta =\frac{BC}{AC}=\frac{12}{13}\]
