Answer:
<h2>90</h2><h2 />
Step-by-step explanation:
see attached image.
internal angle must be equal to 180
- ∠2 + 33 + 57 = 180
- ∠2 = 180 - 57 - 33
- ∠2 = 90
<u>Given:</u>
The given function is 
We need to determine the reflection of f(x) over the x - axis
<u>Reflection over x - axis:</u>
The translation rule to reflect over the x - axis is given by

Reflecting the function over the x - axis, we get;

Multiplying -1 to both sides of the equation, we have;

This can be written as

Hence, the reflection of the function over the x - axis is 
Thus, Option A is the correct answer.
