Answer:
x=12
Step-by-step explanation:
The diagonals are angle bisectors, so 4x+22 = 6x-2
Number 7 I believe the answer is 74.
Percentage error is calculated by
Percentage error = (estimate-real)/real*100%=(115-82.5)/82.5*100%=28.26%
An over-estimate gives a positive error percent, and an underestimate gives a negative error.
Also, dividing by the real value makes it possible to have more than 100% error.
For example, if real cost is $50, and estimated cost is $150, then error percent is (150-50)/50*100%=200%!
0,9x
10%=0,1
100%-10%
1x-0,1x=0,9x
Hiya!
First, translate vertex A to vertex X. Next, rotate angle ABC to align the sides and angles.
How I got this? Simple! Notice how both shapes are the exact same, down to the exact measurements. Now, imagine a four-quadrant grid with (0, 0) is between point C and Y. ABC is in the top left quadrant and XYZ is in the lower right. If you rotated the whole thing, they'd overlap. Vertex A is actually vertex X, theoretically.
If you found this especially helpful, I'd appreciate if you'd vote me Brainliest for your answer, if other people did not provide a helpful answer (but, I'm sure they did!). I want to be able to assist more users one-on-one! :)
