    If \[\text{sin A}=\text{sin C},\]what will be the length of BC?

    A) \[2ft\]

    B) \[4ft\]

    C) \[8ft\]

    D) \[4\sqrt{2}ft\]

    Correct Answer: B

    Solution :

    Given,     \[\sin A=\sin C\]
    In right \[\Delta ABC\]
    \[\frac{BC}{AC}=\frac{AB}{AC}\,\,\,\,\,\,\Rightarrow \,\,\,\,\,\,\,BC=AB=4ft\]
    So, option [b] is correct.
