Answer:
x = 54°
y = 66°
Step-by-step explanation:
x + y = 120° (given)
x = y - 12
Then, y + y - 12 = 120°
(y + y) - 12 = 120°
2y - 12 = 120°
2y = 120 + 12 = 132°
y = 132/2 = 66°
x = y - 12 = 66 - 12 = 54°
There you go :)
Part A is asking you to substitute x for 6 and solve. Part B asks you to substitute x for -4.
No because the perimeter of a rectangle is L×W or (2L+2W) , but the perimeter of a square is S×S×S×S so there is a difference between the two.

Hi, I believe the answer to this problem would be A.
Let me know if I'm wrong though...
