    If the angle of elevation of the top of tower at a distance 500 m from its foot is\[{{30}^{o}}\], then height of the tower is   [Kerala (Engg.) 2002]

    A) \[\frac{1}{\sqrt{3}}\]

    B) \[\frac{500}{\sqrt{3}}\]

    C) \[\sqrt{3}\]

    D) \[\frac{1}{500}\]

    Correct Answer: B

    Solution :

    Let the height be h,   \[\therefore \tan {{30}^{o}}=\frac{h}{500}\]  Þ \[h=\frac{500}{\sqrt{3}}\]
