The sum of the interior angles of a polygon with n sides is select one: a. 180 b. 360 c. 180(n-2)

c. 180(n - 2)

Step-by-step explanation:

Note that the variable (n) equals to the amount of sides there are. You can use it to find the total amount of degrees the shape has.

for example, a triangle has 3 sides:

180(n - 2)

180(3 - 2)

180(1) = 180

This means that the sum of the triangle's interior angles is = 180°

Another example can be an pentagon, which has 5 sides:

180(n - 2)

180(5 - 2)

180(3) = 540

This means that the sum of the pentagon's interior angles is = 540°

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'.

i am pretty sure that the answer is 168
