An old principle of public landscaping says "build sidewalks last." in other words, let the people find their chosen paths and then build the sidewalks on the paths. figure 10.40 shows a campus quadrangle that measures 40 m by 30 m. the locations of the doors of the library, chemistry building, and humanities building are shown. what is the combined length of the new sidewalk (gold lines) that connects the three buildings

step-by-step explanation:

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'.

dont trust me im no expert these losers made me fail a test bro this sucks
