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).

Answer:
6. b. 50
7. d. 12
Step-by-step explanation:
6. 80% is equal to 0.8.
0.8x =40.
Divide 0.8 by 40 to get x.
x=50.
7. If he needs 3 eggs for 30 cookies, we divide 120 by 30 to get 4.
We multiply 4*3 to find the total amount of eggs needed.
4*3= 12
The slope of a perpendicular line is the opposite of the given line.
x -> -x
Find a y-intercept that crosses through the point (0, -2).
y = -x - 2 works!
Now change the equation from slope-intercept form to standard form [ Ax + By = C ].
y = -x - 2
y + x = -2
x + y = -2
Best of Luck!
