cos 70°=____what is the answer rounded to the nearest hundredth

Sagot :

By definition, Cosine is a Trigonometric function.

In this case, you have:

[tex]\cos 70\degree[/tex]

To evaluate it, you can use your calculator. You just need to press the bottom "Cos" and type the angle 70. It'll look in this form:

[tex]\cos (70)[/tex]

To round the result to the nearest hundredth, you can follow these steps:

1. Look at the digit in the Thousandths place.

2. If that digit is less than 5, you only need to remove all the digits to the right of the digit in the Houndredths place.

3. If the digit in the Thousandths place is greater than or equal to 5, you must add 1 to the digit in the Hundredths place and remove all the digits to the right.

Therefore, you get that the answer is:

[tex]\cos 70\degree\approx0.34[/tex]
