Find the length of the missing side. the triangle is not drawn to scale. http://assets.openstudy.com/updates/attachments/55b7acbae4b0c500a11b1b68-lollygirl217-1438196458225-as.jpg I already have the answer: cos(22) = x/11. Remember that cos(angle) = adj/hyp. The adjacent side to the 22 degrees in this case is x and the hypotenuse is obviously 11. Is that correct?

    if you want the angle just take the arccos(adj/hyp) your calculator probably has a button that looks like this \[\cos^{-1}(x)\] this button means arccos

    You would only use arccos if you were trying to find the angle

    your answer will be : cos(22) = x/11 cos(22)*11 = x http://www.wolframalpha.com/input/?i=+cos%2822%29*11+%3D+x just hit approximate form you should get roughly 10.99 degrees
