Answer:
60 degress
Step-by-step explanation:
How I got it:
1. Find out the angel of each side. 360 divded by 6 = 60
2. Get the answer of 60
Advice:
-Make an polygon using paper and rotate it. (Use protractor and ruler if your gonna do it)
Answer:
(b) 1:9
(c) 1:8
Step-by-step explanation:
(b) x*y : kx*ky, so 1:k² with k=3 is 1:9
(c) Assuming the rectangles get a z dimension, the volumes would have a ratio of xyz : xkykzk = xyz : xyzk³ = 1 : k³. With k=2 that is 1:8. But the z was never introduced so this is a bit inconclusive.

Consider expanding the right hand side as
![y=\sqrt[3]{\dfrac{x(x-2)}{x^2+1}}=x^{1/3}(x-2)^{1/3}(x^2+1)^{-1/3}](https://tex.z-dn.net/?f=y%3D%5Csqrt%5B3%5D%7B%5Cdfrac%7Bx%28x-2%29%7D%7Bx%5E2%2B1%7D%7D%3Dx%5E%7B1%2F3%7D%28x-2%29%5E%7B1%2F3%7D%28x%5E2%2B1%29%5E%7B-1%2F3%7D)
Then taking the logarithm of both sides and applying some properties of the logarithm, you have
Now differentiate both sides with respect to 
:
![\dfrac{\mathrm dy}{\mathrm dx}=\dfrac23\dfrac{x^2+x-1}{x(x-2)(x^2+1)}\sqrt[3]{\dfrac{x(x-2)}{x^2+1}}](https://tex.z-dn.net/?f=%5Cdfrac%7B%5Cmathrm%20dy%7D%7B%5Cmathrm%20dx%7D%3D%5Cdfrac23%5Cdfrac%7Bx%5E2%2Bx-1%7D%7Bx%28x-2%29%28x%5E2%2B1%29%7D%5Csqrt%5B3%5D%7B%5Cdfrac%7Bx%28x-2%29%7D%7Bx%5E2%2B1%7D%7D)
