Okay, the question says to find the value of "tan" - I did and it was 40 degrees. But the options are all in fractions... none of which convert to 40. I am stumped... I'm thinking there must be some sort of trick to this that I'm not getting... please help me.
Thank you... I just realized my mistake. I feel a bit silly. But I still need help. So, tan is the opposite side over the adjecent side, which in this triangle - http://i32.tinypic.com/11i21as.jpg - is 10/15. How can I convert this?
