Answer:
I believe it is an acute angle
Answer: 150 degrees
Step-by-step explanation:
The area is 186.03. lw = 15.9(11.7) = 186.03
Given:
The equation of a quadratic function is:

To find:
The equation of the axis of symmetry for the given function.
Solution:
If a quadratic function is
, then the equation of the axis of symmetry is:
...(i)
We have,

Here,
. So, the equation of axis of symmetry by using (i), is
Therefore, the correct option is C.
