Find the value of x. Round to the nearest tenth. The diagram is not drawn to scale. http://assets.openstudy.com/updates/attachments/55b90c83e4b0adef802b862b-lollygirl217-1438191576562-as.jpg I think I have the answer: cos(22°) = x/11 so x = 11cos(22°) sin(68°) = x/11 The result will be the same as sin(68°) = cos(22°)
