Answer:
I don't know what x is, but look below.
Step-by-step explanation:
If x=angle 3, then x=180-102=72
If x=angle 2, then x=102 (Vertical Angles Theorem
Hope I helped!

Answer: Rotate 180 degrees around point B</h3>
Explanation:
Point A(-3,1) moves to A ' (1,1). The line through these two points is y = 1.
Point C(-3,3) moves to C ' (1, -1). The line through these two points is y = -x
These two lines intersect at point B(-1,1) which is the invariant point, aka fixed point. It is the center of rotation.
Notice how points A, B and A' are collinear (i.e. they are on the same line). The same can be said about points C, B and C'.
Because of these two sets of collinear points, it means we have a 180 degree rotation going on.

Answer:
The proportionality constant is 2/5
Step-by-step explanation:
Here, we want to get the proportionality constant
Let us view the two points as being points on a line
The constant of proportionality will be the slope of the line that connects the two points
Mathematically, we can use the formula for the slope of a line
We have this as;
m = (y2-y1)/(x2-x1)
(x1,y1) = (20,8)
(x2,y2)= (25,10)
m = (10-8)/(25-20) = 2/5
Answer:
C. The median for town A, 30°, is less than the median for town B.
Step-by-step explanation:
A box plot can clearly represent the median as a center of the distribution of a data set.
Thus, the median of a box plot is depicted by the vertical line that divides the rectangular box.
Therefore:
Town A Median temperature = 30°
Town B Median temperature = 40°
The standby that best compares their centers is:
C. "The median for town A, 30°, is less than the median for town B."
Multiply by 80 and you will get how many boys play video games daily.
44 is the number of boys who play video games daily.
