Find the length of the missing side. the triangle is not drawn to scale.

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?

Best ResponseYou've already chosen the best response.1if 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

Best ResponseYou've already chosen the best response.1You would only use arccos if you were trying to find the angle

Best ResponseYou've already chosen the best response.1your 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
