    Question

    ∆ PQR is right-angled at Q. If ∠R = 60º, then find

    the value of cosec P.
    A 2 Correct Answer Incorrect Answer
    B 1/2 Correct Answer Incorrect Answer
    C √3 Correct Answer Incorrect Answer
    D 2/√3 Correct Answer Incorrect Answer

    Solution

    ∠Q = 90°
    ∠R = 60°
    The sum of the angle of the triangle = 180°
    90° + 60° + ∠P = 180°
    ∠P = 30°
    Cosec P = Cosec 30° = 2
