    Question

    If (3cos A - sin A) = 2 cos (90° - A), then find the

    value of cot A.
    A 1 Correct Answer Incorrect Answer
    B 2 Correct Answer Incorrect Answer
    C 3/2 Correct Answer Incorrect Answer
    D √3 Correct Answer Incorrect Answer

    Solution

    We have, (3cos A - sin A) = 2 cos (90° - A)

    Or, (3cos A - sin A) = 2 sin A

    Or, 3cos A = 3 sin A

    Or, {(cos A)/(sin A)} = 1

    So, cot A = 1

    Hence, option a.
