    tan y
    A тИЪ3 тАУ 2 Correct Answer Incorrect Answer
    B тИЪ3 тАУ1 Correct Answer Incorrect Answer
    C тИЪ3 + 2 Correct Answer Incorrect Answer
    D тИЪ5 + 1 Correct Answer Incorrect Answer

    Solution

    2sin y + cos y = тИЪ3 sin y siny (тИЪ3-2) = cos y tan y = 1/ (тИЪ3-2) tany = (тИЪ3+2) / (тИЪ3+2) ├Ч (тИЪ3-2) ┬а tany = тИЪ3 + 2 The value of tany is тИЪ3 + 2.
