Finding the Area of a Regular Polygon
The apothem of a regular hexagon measures
8 cm.
Which are true of the regular hexagon? Check all that
apply.
The perimeter of the hexagon is 48 cm.
The measure of the angle formed by the radius and
the apothem is 30°.
The side length of the hexagon is about 4.6 cm.
In a regular hexagon, the radius and side length are
equal in length.
The area of the hexagon is about 221.7 square cm.

B, D and E.

just trust me

I just did it:

-The measure of the angle formed by the radius and the apothem is 30

- in a regular hexagon, the radius and side length are equal in length.

-the area of the hexagon is about 221.7 square cm.

b) well because you get well

for the friend request.

when a figure, such as triangle (xyz) is reflected over the line y = x to create x'y'z' the x-coordinates and y-coordinates of the original image (pre-image) will be reversed for the image. (e.g., (x, y) > (y, x)) this means that the pre-image position of the x- and y-coordinates switch places which in turn provides a mirror like image of the original xyz.  

i notice that when i draw a line segment from x to x', that the points are parallel from each other -- they are exactly across from each other and do not intersect with any other points.  

yes, think i would see the same characteristic if you drew the line segment connecting y with the reflecting line and then y' with the reflecting line because of the essence of reflections. because it is a mirror image, each point was effected the same way which leads me to conclude that they same would apply to y and y'.
