Answer:
I believe the answer is c
Step-by-step explanation:
sin(90-a)=cos
cos = angle adjacent
theta=BC/CA
Suppose for the moment that the inequality holds for all :
Expanding everything gives
In particular, the inequality says that for any choice of . But if and , then while .
So one possible choice of could be and . Then we get
but clearly it's not true that .
