and the perimeter is 
We substitute into the formula to obtain;


To the nearest square inch, we have;

Correct Answer: Option AThe next step in simplification will be to convert the squared term so that it no longer contains a square.
So, we are to simplify the term

Using the half-angle identity we can write:

Using this value, the equation becomes:
Therefore, option A is the correct answer.
That's correct. Now you gotta plug in -5 in for x and get both angles.
