Answer:
Step-by-step explanation:
To solve this problem you must know the formula of subtraction of angles for the function cosx.
The formula is:
We can write 30° as: 45° - 15°
Then:
Using the formula for subtraction of angles we have:
Notice that we have achieved the expression shown in the statement
Finally:
Get n by itself in both inequalities
(This program doesn't allow for regular less than or greater than signs, so for the purposes of this problem I will be using less than or equal to (≤) and greater than or equal to (≥) signs)
Inequality 1:
Inequality 2:
Now that you have both of the n's by themselves, you can put the two inequalities together, like this
Just keep in mind that these are supposed to be regular less than signs
