Answer: [tex]x=10.2[/tex]
Step-by-step explanation:
The triangle shown in the image attached is a right triangle.
Therefore, you can calculate the value of x as you can see below:
[tex]cos\alpha=\frac{adjacent}{hypotenuse}[/tex]
In this case, you have that:
adjacent=x
hypotenuse=11
[tex]\alpha=22\°[/tex]
Therefore, when you substitute values and solve for x, you obtain the following result:
[tex]cos(22\°)=\frac{x}{11}\\\\x=11*cos(22\°)\\x=10.2[/tex]
