The answer is D) 22
X = 4
Length = 4
Width = - 5
Perimeter = 8 + -10
Perimeter = - 2

X = 31
Length = 31
Width = 22
Perimeter = 62 + 44
Perimeter = 106

X = 13
Length = 13
Width = 4
Perimeter = 26 + 8
Perimeter = 34

X = 22
Length = 22
Width = 13
Perimeter = 44 + 26
Perimeter = 70

Answer:

  5.  x = 160; y = 20

  6.  h = 125°; g = i = 55°

Step-by-step explanation:

Vertical angles are found on opposite sides of a point where lines cross. Each angle is formed from rays opposite those of the other angle. Vertical angles are congruent.

5. x° and 160° are vertical angles: x° = 160°

  y° and 20° are vertical angles: y° = 20°

__

6. h° and 125° are vertical angles: h° = 125°

The angles g° and 125° form a "linear pair" so total 180°.

  g° = 180° -125° = 55°

  g° and i° are vertical angles: g° = i° = 55°
