Answer:
144 = each interior angle
Step-by-step explanation:
The sum of the interior angles of a regular polygon is
(n – 2)180
If it is regular with n sides, divide by n to find each interior angle
(n – 2)180
------------------- = each interior angle
n
We know that there are 10 sides so n = 10
(10 – 2)180
------------------- = each interior angle
10
(8)180
------------------- = each interior angle
10
144 = each interior angle
Okay so for the #1 it says that it take 1/2 (half) a day to paint 1/4 of your bedroom and we want to know how many days it would take to paint all of the bedroom, so 4/4 of the bedroom.
We can say that
1/2(number of day) = 1/4(how much you painted)
to paint all of your room you would have to have painted 4/4 of your room
to get to 4/4 i multiplied 1/4 by 4
you do the same thing to 1/2 so 1/2•4=2
So it would take 2 days to paint all (4/4) of your bed room
I dont if im clear but just think about it
If you take half a day to pain 1/4 of your room, in one day you would’ve painted 2/4 of your room, so in one day you paint 2/4 of your room. And in 2 days you paint 4/4 of your room
