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。
