Answer: 10.2 (nearest tenth)

Step-by-step explanation:

For this question, you have to find out whether you are using Sin, Cos, or Tan.

For that, you can use SOH CAH TOA to help you.

SOH-the 'S' is for Sin then the 'O' and the 'H' stands for Opposite over Hypotenuse.

CAH-the 'C' is for Cos and the 'A' and the 'H' is for Adjacent over Hypotenuse.

TOA-the 'T' is for Tan then then 'O' and the 'A' is for Opposite over Adjacent.

Because you have the Adjacent (the side next to the 22°) and the Hypotenuse (the side opposite the right angle) you would be using Cos.

First you would write:

Cos 22=x/11

Then because you want x on it's own you would do the inverse so you would times Cos 22 by 11.

This would be written as:

11 Cos 22=x

So, x=10.2 (nearest tenth)

Hope this helps :)
