Permutation: In a race of 10 students, find the number of ways students can finish 1st, 2nd, and 3rd. In this case the order matters, so it is a permutation.
10 x 9 x 8 = 720 ways
Combination: In a class of 10 students, find the number of ways a group of 3 students can be selected to win a prize. In this case the order doesn't matter, so it's a combination.
10 x 9 x 8 / (3 x 2 x 1) = 120 ways
it is either 5 cm or its 4 cm

Answer:
The sum of the exterior angles of hexagon is 360° .
Step-by-step explanation:
Given as :
For a hexagon , let the sum of exterior angles = x
Now, for any polygon The sum of each exterior angle =
Where n is the number of sides of any polygon
If polygon is a hexagon ,
Then , for hexagon the number of sides = 6
∵ The measure of each exterior angle =
So, For hexagon , n = 6
The measure of each exterior angle =
I. e The measure of each exterior angle = 60°
So, The sum of the exterior angles of hexagon is 60° × 6 = 360°
Hence The sum of the exterior angles of hexagon is 360° . Answer
