I am working through the CALTrans LS/LSIT Review Course (no I am not from CA) and see quite a few type-o's and am wondering about the following problem:
I am using the Law of Cosines with this problem and am ending up with 1/COS A = 0/397.16². Am I doing something wrong? Are one of the sides AB or AC a type-O? The Answer key says the answer = D.
Thanks,
Garry
