How do you find the value of x when cos(22°) is involved, and round it to the nearest tenth?

To find the value of x when you are given cos(22°) and asked to round it to the nearest tenth, follow these steps:

  1. First, calculate the value of cos(22°). You can use a scientific calculator or an online tool for this. Most calculators will allow you to enter the angle directly.
  2. After inputting 22°, you should find that cos(22°) \\approx 0.9272.
  3. Next, to round this value to the nearest tenth, look at the digit in the hundredths place (the second digit after the decimal point). In this case, it is a 2.
  4. Since the digit in the hundredths place is less than 5, you will round down. Therefore, 0.9272 rounded to the nearest tenth is 0.9.

So, the value of x rounded to the nearest tenth is 0.9.
