Apparently, we use "Permutation" when order doesn't matter. In that way, only possible outcomes can be calculated.
P (n, r) = n! ( (n - r)!
Unlike, We use "Combination" when order does matter. Combination gives us all possible values.
C (n, r) = n! / (n - r)! r!
Hope this helps!
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°
