Answer:
17%
Step-by-step explanation:
3/17.95 = 0.167
0.167 × 100 = 16.7 *rounding to 17
12.95 × 0.17 = 3.0515

Since triangle BDE is right, we can check it for special rules: BD is hypotenuse = 20, and BE = 12, both divisible by 4: get 5 and 3... so it's a 3-4-5 special right triangle, the 4×4 = 16 m for side DE.
Since AD bisects angle A, I think then side DG should be congruent with DG. So then
DG = 16 m
![\frac{3}{2} = \frac{2x}{2x+y}](https://tex.z-dn.net/?f=%20%5Cfrac%7B3%7D%7B2%7D%20%3D%20%5Cfrac%7B2x%7D%7B2x%2By%7D%20)
From any proportion, we get another proportion by inverting the extremes (or the means):
![\frac{2x+y}{2} = \frac{2x}{3}](https://tex.z-dn.net/?f=%20%5Cfrac%7B2x%2By%7D%7B2%7D%20%3D%20%5Cfrac%7B2x%7D%7B3%7D%20)
= k
so we have:
2x=3k
2x+y=2k therefore:
3k+y=2k
y= - k
x=
![\frac{3}{2} k](https://tex.z-dn.net/?f=%20%5Cfrac%7B3%7D%7B2%7D%20k)
![\frac{x}{y}](https://tex.z-dn.net/?f=%20%5Cfrac%7Bx%7D%7By%7D%20)

![\frac{3}{2}](https://tex.z-dn.net/?f=%20%5Cfrac%7B3%7D%7B2%7D%20)
The corect answer is A. -3/2
or:
![\frac{3}{2} = \frac{2x}{2x+y}](https://tex.z-dn.net/?f=%20%5Cfrac%7B3%7D%7B2%7D%20%3D%20%5Cfrac%7B2x%7D%7B2x%2By%7D%20)
From any proportion, we get another proportion by inverting the extremes and the means:
![\frac{2x+y}{2x} = \frac{2}{3}](https://tex.z-dn.net/?f=%20%5Cfrac%7B2x%2By%7D%7B2x%7D%20%3D%20%5Cfrac%7B2%7D%7B3%7D%20)
We use a property of proportions:
![\frac{a}{b} = \frac{c}{d}](https://tex.z-dn.net/?f=%20%5Cfrac%7Ba%7D%7Bb%7D%20%3D%20%5Cfrac%7Bc%7D%7Bd%7D%20)
where a, d are extremes and b,c are means and the product of the extremes equals the product of the means (a*d=b*c),
so we have
![\frac{a-b}{b} = \frac{c-d}{d}](https://tex.z-dn.net/?f=%20%5Cfrac%7Ba-b%7D%7Bb%7D%20%3D%20%5Cfrac%7Bc-d%7D%7Bd%7D%20)
or
![\frac{a+b}{b} = \frac{c+d}{d}](https://tex.z-dn.net/?f=%20%5Cfrac%7Ba%2Bb%7D%7Bb%7D%20%3D%20%5Cfrac%7Bc%2Bd%7D%7Bd%7D%20)
(you can check this also by "the product of the extremes equals the product of the means")
![\frac{2x+y}{2x} = \frac{2}{3}](https://tex.z-dn.net/?f=%20%5Cfrac%7B2x%2By%7D%7B2x%7D%20%3D%20%5Cfrac%7B2%7D%7B3%7D%20)
![\frac{(2x+y)-2x}{2x} = \frac{2-3}{3}](https://tex.z-dn.net/?f=%20%5Cfrac%7B%282x%2By%29-2x%7D%7B2x%7D%20%3D%20%5Cfrac%7B2-3%7D%7B3%7D%20)
![\frac{y}{2x} = \frac{-1}{3}](https://tex.z-dn.net/?f=%20%5Cfrac%7By%7D%7B2x%7D%20%3D%20%5Cfrac%7B-1%7D%7B3%7D%20)
3y = - 2x
