The 5x and the combination of (40° + x) are "vertical angles".
Vertical angles are equal.
So
5x = 40° + x
Subtract 'x' from each side: 4x = 40°
Divide each side by 4 : x = ?
The functions which are even are symmetric to y-axis. By even functions, it means that f(x) = f(x) for all the domain values. Thus even functions for example, x^2, 1+x^2, cosx, x^4 all follow the conditions i.e. f(x) = f(x) and thus they are symmterical to y-axis.

3 miles X 4 times a week is =12 miles a week so 12 miles X 6 =72 miles
Answer:
28
Step-by-step explanation:
When there is a - symbol directly outside parenthesis, you always assume a 1 to be there.
-(-28) = -1(-28)
-1 × -28 = 28
