Answer:
Step-by-step explanation:
The sum of the interior angles of an n gon is found by using the following formula.
(n-2)*180 = sum of the interior angles.
(n - 2) * 180 = 3960 Divide by 180
(n - 2) 180/180 = 3960/180 Show the division
n - 2 = 22 Add 2 to both sides.
n -2+2=22+2 Combine
n = 24
======================================
To find the size of each angle, use
(n - 2)*180/n
(24 - 2)*180/24
22 * 180/24
3960/24 = 165
===========
another way
===========
You already know there are 24 sides. You are given the sum of the interior angles as 3960
All you really need to do is 3960/24 = 165
The answer is A.
Divide 300 by the number of faces of a cube.
Since there are 6 faces on a cube then we divide it.
300 ÷ 6 = 50.
So exactly 50 times.
Hope this helps :)
You need to divide 122 by 10, then you multiply your answer by 10 and see if you get 122. So 122 divided by 10 = 12.2, then 10 x 12.2= 122.
Answer:
4,500
Step-by-step explanation:
To find the number of students majoring in economics, you must turn 90% into a decimal making it .9.
Then you multiply the decimal to how many students there are (5000x.9) and that gives you 4,500.
