Answer:
4
Step-by-step explanation:
Value of cos(x+π) =
Given cosine of x =
i.e., cos(x) =
Also cos() = . So x = .
We need to find cos(x+π) = cos().
But its value is not easy to find. So we use trigonometric formulas.
We have the trigonometric formula, cos (x+π) = - cos(x) = - =
Cos(x+π) lies in the 3rd quadrant. So there cosine has negative values. That is why, cos (x+π) = - cos(x).

The answer you are looking for is C, that is the best option that i see by looking at the graph and your answer choices. hope this helps and sorry about the wait for an answer.
I'm guessing the total amount of degrees is 360 degrees.
67 + 130 + 72 = 269
360 - 269 = 91
Answer = 91°
Hope this helped☺☺
Do you know the what the the slope intercept form is?
