    Assignment:Find the solution set of inequality 1.7325*h^2-228.9*h-165.33 ≤0 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
        1.7325 * h ^ 2 - 228.9 * h - 165.33 ≤0         (1)

---

    From inequality(1)：
         -0.718374 ≤ h ≤ 132.839587

---

    The final solution set is :
         -0.718374 ≤ h ≤ 132.839587
