Best ResponseYou've already chosen the best response.1Knowing w now, you now know that cos x=4/w. you know w, get x.

Best ResponseYou've already chosen the best response.0ok \[\sin (30)=\frac{ w }{ 6 }\] \[(6)*\sin 30=\frac{ w }{ 6 }*6\] \[6\sin 30=w \] w=3

Best ResponseYou've already chosen the best response.1Now that you found w, use \(\large \cos(\theta) = \frac{w}{4}\)

Best ResponseYou've already chosen the best response.1sorry, \(\large \theta = x\). So \[\large \cos(x) = \frac{3}{4}\]\[\large x = \cos^{1} \left(\frac{3}{4}\right)\]

Best ResponseYou've already chosen the best response.1if cos x= 3/4 , punch in your calculator arccos(3/4) or equivalently, cos^1(3/4)

Best ResponseYou've already chosen the best response.1arccos or cos^1 is a function which returns degree or radians to fulfill the cos ratio. good job.
