    Assignment:Find the solution set of inequality tan30 >(-2.47sin1.5x-10)/(20√6+21.65+21.65cos1.5x) .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
         tan 30 > ( -2.47 * sin 1.5 * x - 10 ) / ( 20 * √ 6 + 21.65 + 21.65 * cos 1.5 * x )         (1)
        From the definition field of divisor
         20 * √ 6 + 21.65 + 21.65 * cos 1.5 * x ≠ 0        (2 )

---

    From inequality(1)：
         -60.235426 < x < -46.125773
    From inequality(2)：
         x < -46.125773 或  x ＞ -46.125773

---

    From inequalities (1) and (2)
         -60.235426 < x < -46.125773     (3)

---

    The final solution set is :
         -60.235426 < x < -46.125773
