I'm not sure if you were supposed to add two numbers together to get five? If that's the case the answer would be 5/3. If it's not i'm sorry, I tried.
Since it is an equilateral triangle, all of the sides are the same length.
So, x=14 :)
Hope this helps!
There are 22 fourths in 5 1/2
For this case we have the following function:

We want to find the inverse of the function.
The first thing we should do is rewrite the function:

From here, we clear the value of x.
We have then:

Then, returning the variable changes, we have that the inverse function is:

Answer:
The inverse function of f (x) is:
