Column A Column B
5x x+y

选项 A、if the quantity in Column A is greater
B、if the quantity in Column B is greater
C、if the two quantity are equal
D、if the relationship cannot be determined from the information given

答案 C

解析本题的正确答案为(C)。从图中可知，直角三角形的一条直角边等于2，其斜边等于4，因此可以推知x=30(30o所对的直角边等于斜边的一半)，y=30+90=120，所以5x=x+y。
