Somehow I got 1 for every answer.......Please help!!!

I'm solving for x, y, and z. I did the sin, cos, and tan which is how I got 1 for every answer. Either my calculator has gone psycho or my math is off :/

If you could, please help!!! Diagram's in the comments!

first one $x$ is $\tan^{-1}(\frac{28}{45})$ which i doubt is 1

here is the answer in both degrees and radians http://www.wolframalpha.com/input/?i=arctan%2828%2F45%29

But I have to round the values to the nearest whole number so the other two still come out to 1.That's the correct answer then?
