According to the trigonometric functions, we can see that angle x can be found through the one that involves the adjacent side and the hypotenuse, which in this case is the cos,
[tex]cos(x)=\frac{27}{30}[/tex]
then, if we apply the inverse we can find the value of x,
[tex]\begin{gathered} cos^{-1}(cos(x))=cos^{-1}(\frac{27}{30}) \\ x\cong25.8 \end{gathered}[/tex]
Answer:
[tex]x\cong25.8[/tex]
