Answer:
x should equal 39 because 102+39=141 so subtract that from 180 like so. 180-141 which equal 39 the answer.
Those are not equivalent.

Answer:
![f[2-f^{-1}(x)]=x](https://tex.z-dn.net/?f=f%5B2-f%5E%7B-1%7D%28x%29%5D%3Dx)
Step-by-step explanation:
Given function is,
f(x) = ![\frac{x-1}{2}](https://tex.z-dn.net/?f=%5Cfrac%7Bx-1%7D%7B2%7D)
Equation form of the function will be,
y = ![\frac{x-1}{2}](https://tex.z-dn.net/?f=%5Cfrac%7Bx-1%7D%7B2%7D)
Interchange x and y,
![x=\frac{y-1}{2}](https://tex.z-dn.net/?f=x%3D%5Cfrac%7By-1%7D%7B2%7D)
Solve for y,
y = 2x + 1
Therefore, inverse of the function 'f' will be,
![f^{-1}(x)=2x+1](https://tex.z-dn.net/?f=f%5E%7B-1%7D%28x%29%3D2x%2B1)
Now
= 2 - [2x + 1]
= -2x + 1
Value of
= f(2x + 1)
From the given function,
f(2x + 1) = ![\frac{(2x+1)-1}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B%282x%2B1%29-1%7D%7B2%7D)
= x
Therefore, value of
