Answer:

Step-by-step explanation:

If you are looking for a missing angle measure, you use the 2nd button and the cos button. Make sure, first off, that your calculator is in "degree" mode by hitting the "mode" button and making sure that the "degree" is highlighed and not the "radian". Then hit "clear". Once you know that you are in the correct mode, hit "2nd" then "cos" and you will see this on your screen:

$cos^{-1}($

Inside the parenthesis you will enter your decimal, so it looks like this now:

$cos^{-1}(.7431$

You do NOT have to close the parenthesis, but you can if you want to. Then hit "enter" to get that the angle that has a cosine of .7431 is 42.0038314 or, to the nearest degree, 42

What is the value of |-3.25| And |-4.25|

Yakvenalex [24]

The values are |-3.25| = 3.25 and |-4.25| = 4.25

<h3>How to determine the values of the expressions?</h3>

The expressions are given as

|-3.25| and |-4.25|

The above expressions are absolute value expressions

And as a general rule, an absolute value expression, when evaluated must follow the following rule

|±a| = a

Using the above as a guide, we have

|-3.25| = 3.25
