[ 1/1Inequality]
    Assignment:Find the solution set of inequality 0 <180-2x <180 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 2 inequalities：
        0 <180 - 2 * x         (1)
        180 - 2 * x <180         (2)

---

    From inequality(1)：
         x < 90
    From inequality(2)：
         x ＞ 0

---

    From inequalities (1) and (2)
         0 < x < 90     (3)

---

    The final solution set is :
         0 < x < 90
