Remember the definition of vertical angles.
The angle between 7x+7 and 112 are vertical. They are congruent and with the same measure.
7x +7= 112
Subtract 7 on both sides.
7x= 105
Divide both sides by 7.
x= 15
I hope this helps!

Step-by-step explanation:
6+[11-{10+2-(8×2+1-3×4)}]
6+[11-{10+2-(8×2+1-3×4)}]6+[11-{10+2-(12)}
6+[11-{10+2-(8×2+1-3×4)}]6+[11-{10+2-(12)} ]6+[11-[10+2-12}]
6+[11-{10+2-(8×2+1-3×4)}]6+[11-{10+2-(12)} ]6+[11-{10+2-12}]6+[11-{0}]
6+[11-0]
6+[11]
6+11

Answer:
![x=8\ in](https://tex.z-dn.net/?f=x%3D8%5C%20in)
Step-by-step explanation:
we know that
If NO is parallel to KJ
then
Triangles LNO and LKJ are similar by AA Similarity Postulate
Remember that
If two figures are similar, then the ratio of its corresponding sides is equal
so
![\frac{LO}{LJ}=\frac{LN}{LK}](https://tex.z-dn.net/?f=%5Cfrac%7BLO%7D%7BLJ%7D%3D%5Cfrac%7BLN%7D%7BLK%7D)
substitute the values
![\frac{x-4}{x-4+x}=\frac{x-3}{x-3+x+2}](https://tex.z-dn.net/?f=%5Cfrac%7Bx-4%7D%7Bx-4%2Bx%7D%3D%5Cfrac%7Bx-3%7D%7Bx-3%2Bx%2B2%7D)
![\frac{x-4}{2x-4}=\frac{x-3}{2x-1}\\ \\(x-4)(2x-1)=(x-3)(2x-4)\\ \\2x^{2}-x-8x+4=2x^{2}-4x-6x+12\\ \\-9x+4=-10x+12\\ \\10x-9x=12-4\\ \\x=8\ in](https://tex.z-dn.net/?f=%5Cfrac%7Bx-4%7D%7B2x-4%7D%3D%5Cfrac%7Bx-3%7D%7B2x-1%7D%5C%5C%20%5C%5C%28x-4%29%282x-1%29%3D%28x-3%29%282x-4%29%5C%5C%20%5C%5C2x%5E%7B2%7D-x-8x%2B4%3D2x%5E%7B2%7D-4x-6x%2B12%5C%5C%20%5C%5C-9x%2B4%3D-10x%2B12%5C%5C%20%5C%5C10x-9x%3D12-4%5C%5C%20%5C%5Cx%3D8%5C%20in)
No they are not quivalent
