    Question

    (cos5°+sin5°)/(cos5°-sin5°) is equal

    to:
    A tan5┬░ Correct Answer Incorrect Answer
    B cot5┬░ Correct Answer Incorrect Answer
    C tan50┬░ Correct Answer Incorrect Answer
    D tan40┬░ Correct Answer Incorrect Answer

    Solution

    (cos5°+sin5°)/(cos5°-sin5°) Divide the numerator and denominator by cos5° (1+tan5°)/(1-tan5°) (tanтБбуАЦ45°уАЧ + tan5°)/(1-tan45° ×tanтБбуАЦ5°уАЧ ) tan (A + B) = (tanA°+tanB°)/(1-tanA°+tanB°) tan (45 + 5) = tan 50
