Answer: 48
Step-by-step explanation:
Given
Trapezoid DEFG is dilated by a scale factor of
![E'F'=32](https://tex.z-dn.net/?f=E%27F%27%3D32)
Suppose the length of EF is ![x](https://tex.z-dn.net/?f=x)
Multiply the side length of DEFG by
to form E'F'
![\Rightarrow E'F'=x\times \dfrac{2}{3}\\\\\Rightarrow 32=x\times \dfrac{2}{3}\\\\\Rightarrow x=16\times 3\\\Rightarrow x=48](https://tex.z-dn.net/?f=%5CRightarrow%20E%27F%27%3Dx%5Ctimes%20%5Cdfrac%7B2%7D%7B3%7D%5C%5C%5C%5C%5CRightarrow%2032%3Dx%5Ctimes%20%5Cdfrac%7B2%7D%7B3%7D%5C%5C%5C%5C%5CRightarrow%20x%3D16%5Ctimes%203%5C%5C%5CRightarrow%20x%3D48)
![\therefore EF=48](https://tex.z-dn.net/?f=%5Ctherefore%20EF%3D48)
Answer:
The solution would be (6, 2)
Step-by-step explanation:
In order to solve this using elimination, simply add the two equations together.
2x + 3y = 18
3x - 3y = 12
-----------------
5x = 30
x = 6
And now that we have the value for x, we can solve for y.
2x + 3y = 18
2(6) + 3y = 18
12 + 3y = 18
3y = 6
y = 2
Answer:
ecd and 25 degrees
Step-by-step explanation:
ecd is dce but is reverse order. CBE angle is 180 degrees(abe is a straight line) minus 155 degrees which is 25 degrees
