## anonymous one year ago 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

Okay thank you.

12. Australopithecus

oops you are looking for x nvm

13. Australopithecus

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

14. Australopithecus

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

sorry 10.199
