Triangle cde is an isosceles triangle with cd congruent to de. if cd equals 9x - 25, de equals 6x + 8, ce equals 10 x - 73, find x and the measure of each side

The value of x is 11 and the measure of each sides are, 74 cm,74 cm and 37 cm.

Explanation:

It is given that in triangle CDE is an isosceles triangle with CD congruent to DE. If CD equals 9x - 25, DE equals 6X + 8, CE equals 10 x - 73.

Since,

Separate like terms and combined them.

Therefore, the value of x is 11.

The measures of all sides are,

Therefore the measure of each sides are 74 cm,74 cm and 37 cm.

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'.

answer: 94

step-by-step explanation: 79+91+92+94+94 = 450 divided by 5 (since there are 5 number that are being added) = 90
