    In the given right angles triangle XYZ. What is the value of \[\mathbf{secx}+\mathbf{tan}\text{ }\mathbf{x}\]?

    A) \[\frac{1}{\sqrt{6}}\]

    B) \[\sqrt{6}\]

    C) \[2\sqrt{6}\]

    D) \[\frac{\sqrt{6}}{2}\]

    Correct Answer: B

    Solution :

    (b): \[sec\,X=\frac{7}{2\sqrt{6}}\] \[\And \,tanX=\frac{5}{2\sqrt{6}}\] \[\therefore sec\,X+tan\,X=\frac{7}{2\sqrt{6}}+\frac{5}{2\sqrt{6}}=\frac{12}{2\sqrt{6}}=\sqrt{6}\]
