Since you have the hypotenuse and the adjacent length, you have to use the trigonometric ratio cosine to
solve for x. Formulating the equation we have:
[tex]\begin{gathered} \cos (x)=\frac{\text{ adjacent length}}{\text{hypotenuse}} \\ \cos (x)=\frac{9}{14}\text{ (Replacing the values)} \\ \cos ^{-1}(\cos (x))=\cos ^{-1}(9/14)\text{ (Using the inverse function of cosine)} \\ x\text{ = 49.99}5\text{ (Dividing 9 by 14 and using the inverse function of cosine)} \\ \text{The answer would be 50\degree{}rounded to the nearest integer. } \end{gathered}[/tex]
