50° is the answer to your question.
Answer:
c
Step-by-step explanation:
The inverse of this function is y = x - 
You can find the inverse of any function by switching the x and y values and then solving for the new y value. Once you've done that, what will be left over is the inverse function.
y =
----> Swap x and y
x =
-----> Subtract 3/4 from both sides.
x -
= y ----> rearrange to appropriate order
y = x - 
And that is your inverse function.
