The answer is 9 because there are 9 types of fabric and the are all 1/5 yard
You will need a graduated scale and you measure.. it will be something like x ≈ 5.2 or 5.3 approximately
You can see in the picture below what you need to find. It is the red point in the picture
Good luck
First we solve this equation:
x = cos^-1(0) = pi/2 and 3pi/2
Now, this is the answer for angles between 0 and 2pi
but there are "negative angles" and angles larger than 2pi
so the general solution that includes all of these cases is:
x = pi/2 + n*pi
here n is any integer.
