the sum of the angles in an ngon (a polygon with n sides) is (n-2)*180
so an octagon has 8 sides and has a sum total of (8-2)*180=1080 degrees
if each of 7 angles is 132, then 1080=?+7*132
1080=?+924
156=?
the 8th angle is 156 degrees
Answer:
-14.53
Step-by-step explanation:

Answer: There are 45 combinations.
Step-by-step explanation:
If the order in which you watch the episodes does not matter, then we can use the combinatory defined as:
If we have N elements, and we want to make groups of K elements, we have
combinations.
In this case, we have a total of N = 10 episodes, and we want to make groups of K = 2.
Then we have:
There are 45 combinations.
Quotient, implies division, so the quotient of 18 and 2 is 6:
18/2=6
Sum implies addition, so the sum of 22 and 9 is 31:
22+9=31
Now we can subtract the quotient of 18 and 2, '6', from the sum of 22 and 9, '31'.
31-6=25
Answer=25
