Answer:
1080°
Step-by-step explanation:
sum = 180 ( n - 2)
note that octagon has 8 sides
therefore
sum = 180 ( 8 - 2)
sum = 1080°

Answer:
50 R 84
Step-by-step explanation:
I don't know how to explain but I'll try my best.
Because 195 is 3 digits, look at the first three digits of the number we are dividing by. In this case it would be:
983
983/195 is about 5 ish. Notice how it's not a perfect number and there is a remainder of 8.
Since we took out the 195, there is only the 4 remaining. Because we had a remainder of 8 from the first part, the 8 would be in the tenth category. Add the 80 and the 4 together, and you get 84.
Because 84 is smaller than 195, you cannot divide them without carrying over a number. Since they want a remainer, your answer would be 50 R 84.
If you want to check, simply multiply the divider and the number you got, (195 and 50), then add 84 to it.
195*50 = 9750
9750 + 84 = 9834
Think of it like this, if there are 13 cards numbered 1-13 and you need to find the probability of pulling a multiple of 3.
Then start by laying out all your options.
1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13
Then find all of the multiples of 3
3, 6, 9, 12
There are 4 multiples of 3 out of all of the cards so you have a 4 out of 13 chance to pull a card with a multiple of 3 on it.
Answer = 4/13
