    It is supposed to be Tan(27)= 34/x. I can go into more detail if you would like on why it is like that.

    First, do you have a calculator that will let you solve for it?

    You have to solve for x, so multiply both side by x. That should leave you with Tan(27) x = 34

    Divide both sides by Tan(27). You will get x= 34/Tan(27)

    How did you enter it into your calculator? You should be able to do 34/tan(27) and get the answer.

    yes so 57.6 over 33.8

    It is the other way around. 33.8/57.6 The adjacent side goes over the hypotenuse.

    Ok so 33.8 divided by 57.6

    Yes. Divide it first. You will get something along the lines of .5868... After that, press 2ND on your calculator, then COS, then 2ND again, and the press the (-) button at the bottom. It will put in your previous answer and should give you the correct answer for the problem.

    I couldn't get it on the computer calculator, but if you go to web2.0calc.com/ you should be able to use a scientific calculator that will let you do the 2ND function. If you get there, just follow the same steps as before.

    After you press acos, just hit = and you should get the answer. Sorry for the confusion.
