Answer:
Infinitely many solutions.
Step-by-step explanation:
x+2y=-1
2x+4y=-2
-----------------
x=-1-2y
2(-1-2y)+4y=-2
-2-4y+4y=-2
-2+0=-2
-2=-2
infinitely many solutions
Answer:

Answer:
32.7 degrees
Step-by-step explanation:
The total exterior angle of any polygon is 360 degrees
Each exterior angle can be calculated by dividing this total by the number of sides
So we have each measure as 360/n
where n is the number of sides
here, we have n = 11
So we have each exterior angle as:
360/11 = 32.7 degrees
