In the triangle below, what ratio is cos? A.) 12/13 B.) 5/13 C.) 13/5 D.) 12/5 I'll upload the picture in a minute, but what I'm getting is Cosθ= 1.5/3.9 but that's not a choice? Would you guys just take out the decimal point, since the answers correspond with the numbers if there weren't decimal points? If I do that, I get B, but I don't want to be wrong.

    after that you should be able to see that 15/39 can be reduced

    That's what I got, I was just confuse why they would put the decimal points at all. I just wanted to make sure I wasn't going to answer completely wrong. Thanks!
