The sum of the interior angles of a polygon is.

Sum = 180(n-2) where n is the number of sides

Thus 180(n-2) = 3780

n-2=3780/180 =21

⇒ n = 21+2 = 23

number of sides is 23

Sum of interior angles of n sided polygon = (n - 2) * 180

(n - 2) 180 = 3780

180n - 360 = 3780

180n =  4140

n = 4140 / 180  = 23 sides  Answer

State the additive property of zero using the variable b.
Juli2301 [7.4K]

Answer with Step-by-step explanation:

We are given a variable b

We have to state the additive property of zero using the variable b.

Additive property of zero: It states that when any number b is added to zero then we get  sum is equal to number itself.

Mathematical representation:

b+0=0+b=b

Suppose, a number  b=9

Then, 9+0=9

0+9=9

This property is called additive property of zero because when 9 is added to 0 then we get sum equals to 9.

Answer:

I believe its 20% or 20/100 or 1/5

i mean, 20% is 20/100 or 1/5. the number already a fraction. the denominator is out of 100.

20% = 20/100

then you change it to simpliest form.

20 / 20 = 1

100 / 20 = 5 = 1/5
