http://photoshare.shaw.ca/image/6/8/e/231110/q-0.jpg I cant find theta. Anyone help me out here? x=theta I've tried making Fab=(160cosx)/cos40 Then plugging it in into the second equation, we get 160cosxtan40+160sinx-200=0 160(cosxtan40+sinx)=200 cosxtan40+sinx=1.25 Is there a trig identity here? Far as I can get. I also tried cosx=(Fabcos40)/160 sinx=200-(Fabsin40) Then tanx= [200/(Fabsin40)]-tan40, but no way to eliminate Fab. Or at least I can't. Thanks in advance.
