Given is a right triangle.
We know that the ratio of cosine is defined as "adjacent" over "hypotenuse".
With respect to the angle given, we see that
• x is the adjacent side
,
• 7 is the hypotenuse
Thus, we can write:
[tex]\cos 35=\frac{x}{7}[/tex]
Now, we can cross-mutliply and figure out the length of "x". Shown below:
[tex]\begin{gathered} \cos 35=\frac{x}{7} \\ x=7\times\cos 35 \\ x=5.73 \end{gathered}[/tex]Answerx = 5.73
