Answer:

Sum=720  x=105 degrees  Angle H=110 degrees   Angle I= 100 degrees   Angle K= 135

Step-by-step explanation:

*A hexagons angles add up to 720

*This is a hexagon

*No matter  how the hexagon is shaped, it's still going to add up to 720

  1. Combine all of the angles (known and unknown) into an equation to equal 720
  2. 140+105+(x+30)+130+(x-5)+(x+5)=720
  3. remove parentheses
  4. 140+105+x+30+130+x-5+x+5=720
  5. Combine like terms and simplify
  6. 3x+405=720
  7. subtract 405 from both sides
  8. 3x=315
  9. divide by 3 on both sides
  10. 3x/3=315/3
  11. x=105
  12. Angle H = x+5
  13. Plug in x
  14. 105+5=110
  15. Angle H= 110 degrees
  16. Angle I = x-5
  17. pug in x
  18. 105-5=100
  19. Angle I= 100 degrees
  20. Angle K= x+30
  21. plug in x
  22. 105+30=135
  23. Angle K= 135 degrees

Step-by-step explanation:

We believe the proof <em>statement — reason</em> pairs need to be ordered as shown below

  Point F is a midpoint of Line segment AB Point E is a midpoint of Line segment AC — given

  Draw Line segment BE Draw Line segment FC — by Construction

  Point G is the point of intersection between Line segment BE and Line segment FC — Intersecting Lines Postulate

  Draw Line segment AG — by Construction

  Point D is the point of intersection between Line segment AG and Line segment BC — Intersecting Lines Postulate

  Point H lies on Line segment AG such that Line segment AG ≅ Line segment GH — by Construction

__

  II Line segment FG is parallel to line segment BH and Line segment GE is parallel to line segment HC — Midsegment Theorem

  IV Line segment GC is parallel to line segment BH and Line segment BG is parallel to line segment HC — Substitution

  I BGCH is a parallelogram — Properties of a Parallelogram (opposite sides are parallel)

  III Line segment BD ≅ Line segment DC — Properties of a Parallelogram (diagonals bisect each other)

Answer:

To  get system B, the SECOND equation in system A was replaced by the sum of that equation and the FIRST equation multiplied by FOUR. The solution to system B IS de same as the solution to system A

Step-by-step explanation:

x-y=3  equation 1

-2x+4y=-2   equation 2

so, multiplying by four the equation 1 we have

4x-4y=12   equation 3

later sum equation 3 and equation 2 we have

2x=10
