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:
95$
Step-by-step explanation:
Alli sells 5 bars, for each bar she earnd 5$ so she earns 5*5=25$
Janet sells 7 mugs, and for every mug she earns 10$ (twice then Alli), so she earns 7*10=70$
Together: 25+70=95$
