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.
