Given:
The adjacent side is 16.
The hypotenuse side is x.
The angle is 40 degrees.
To find:
The value of x.
Explanation:
Using the trigonometric ratio for the cosine formula,
[tex]\begin{gathered} \cos40^{\circ}=\frac{16}{x} \\ x=\frac{16}{\cos40^{\circ}} \\ x=20.89 \end{gathered}[/tex]
Thus, the value of x is 20.89.
Final answer:
The value of x is 20.89.
