Answer:
(A)
Step-by-step explanation:
Given a set with "n" number of elements, the collection of all subsets of the set is referred to as the Power set of the given set.
To find the number of possible subsets of any set, we use the formula:
Take for example the set: A={2,3,4)
A has 3 elements, therefore n=3
The number of possible subsets of A is: 
Answer:
60 sides
Step-by-step explanation:
The formula for the sum of the interior angles of a polygon with n sides is 180(n -2). The problem also tells you that each angle is 174, so the sum of the interior angles would also be 174n.
Then, you get the equation
180(n - 2) = 174n
180n - 360 = 174n
6n = 360
n = 60 sides.
There are alot it depeneds of what is the number :)
