Answer:
Step-by-step explanation:
<h2>Hello!</h2>
The answer is:
The rewritten expression is:
<h2>Why?</h2>
To solve this problem we need to use the trigonometric identity of the double angle for the cosine which states that:
Also, if we want to rewrite only with terms of cos(x) and sin(x), we can apply the following property:
So, rewriting the trigonometric equation, we have:
Then, we are given the expression:
Now, rewriting the given expression with only sin(x) and cos(x), we have:
Hence, the answer is:
Have a nice day!

Answer:
4140
Step-by-step explanation:
use (n-2)180
n = number of sides
(25-2)180
(23)180
4140
