Which is the correct equation you would use to solve for the missing angle?

• $\cos\ 9\ =\frac{x}{11}$
  

• $\cos\ \theta=\frac{11}{9}$

• $\cos\theta=\frac{9}{11}$
  

• $\cos^{-1}\theta=\frac{9}{11}$

What would your first step be in solving for  $\theta$  in the following equation  $\cos\theta=\frac{9}{11}$  ?

• divide each side by  $"\cos"$  
  

• multiply each side by $"\cos"\$ 

• take the inverse $\cos$ of each side  $\left(\cos^{-1}\right)$
