Answer:
steps below
Step-by-step explanation:
Are you going to solve the value of A or just a proof the equation
cos 2A = cos² A - sin² A
2cos²A-cos2A-1 = 2cos²A - (cos² A - sin² A) - 1 = cos² A + sin² A - 1
2cos²A-cos2A-1 = 1 - 1 = 0
A: 90° or 270° or 450° .....

To find the perimeter you would add up all of the sides, so:
5x - 2 + 3x + 4 + x - 10
Now you combine the like terms
5x + 3x + x = 9x
-2 + 4 - 10 = -8
So your final answer is C) 9x - 8. I hope this helps!
9 / 15
9 / 3 = 3
15 / 3 = 5
so 3 / 5
60/100
6/10
