Table schema:
CREATE TABLE table_name_84 (height VARCHAR, name VARCHAR, built VARCHAR, rank VARCHAR, floors VARCHAR)

Question: What is Height, when Rank is less than 20, when Floors is greater than 9, when Built is 2005, and when Name is The Edge (C)?
SQL: SELECT height FROM table_name_84 WHERE rank < 20 AND floors > 9 AND built = 2005 AND name = "the edge (c)"
