Step-by-step explanation:
I don't know how to show you in Venn diagram.
Ax+by=c
y=x+3
subtract x from both sides
Y-x=x-x+3
Y-x=3
-1•(y-x)=-1•3
-y+x=-3
Reorder:
X-y=-3
I’m not sure if it’s 100% correct but that’s all I can do
The answer to your question is 443.2 as the mean is the average
Answer:
36°
Step-by-step explanation:
From the question,
The sum of the exterior angle of a polygon = 360
From the diagram. the polygon is Decagon
Note: A Decagon is a polygon with 10 sides.
number of sides = 10 .
The exterior angle of a regular polygon = sum of the exterior angle/number of sides.
Exterior angle = 360/10
Exterior angle = 36°
Hence the measure the single extrior angle = 36°
