To find the value of x when you are given cos(22°) and asked to round it to the nearest tenth, follow these steps:
- 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.
- After inputting 22°, you should find that cos(22°) \\approx 0.9272.
- 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.
- 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.
