Answer:
<u><em>30cm</em></u>
Step-by-step explanation:
Given data
When are square is cut diagonally into two parts
The resulting shape is a triangle
hence the area of the square = 50+50 = 100cm^2
The length of each side of the square = √100= 10cm
likewise the diagonal of the square = 10cm
<u><em>Hence the perimeter of the resulting triangle= 10+10+10= 30cm</em></u>

Answer:
Step-by-step explanation:
Consecutive interior angles are supplementary.
   (x -20)° +(4x +15)° = 180°
   5x = 185 . . . . . . . . . . . . . . divide by °, add 5
   x = 37 . . . . . . . . . . . . divide by 5
__
   74° +(5y -4)° = 180°
   5y = 110 . . . . . . . . . . . divide by °, subtract 70
   y = 22 . . . . . . . . . . divide by 5

Answer:
b = 34°
Step-by-step explanation:
b + 115° + 31° = 180°
 b + 146° = 180
  b = 180° - 146°
 b = 34°
