The sum of the measures of all exterior angle in a polygon with n sides is always
.
Nonagon is a polygon with 9 sides. If this nonagon is regular or equiangular, then all interior angle are congruent, and therefore all exterior angles are congruent. Then the measure of each exterior angle is
.
Percentage of pages of a book read by Katie = 32%
Total number of pages of the book read by Katie = 80
Let us assume the number of pages that the book has = x
Then
(32/100) * x = 80
32x = 80 * 100
32x = 8000
x = 8000/32
= 250
So the book has a total of 250 pages in it.
Then
The number of pages that Katie still needs to read = 250 - 80
= 170
So Katie needs to read 170 more pages in the book.

Step-by-step explanation:

$ 2772 is paid in state income tax
<em><u>Solution:</u></em>
Given that, Tina lives in a state that charges her 4.5% state income tax on her federal taxable income
Federal taxable income = $61,600
<em><u>To find: Amount paid by Tina in state income tax</u></em>
Tax rate = 4.5 %
<em><u>Which means, 4.5 % of $61,600 is paid as tax</u></em>

Here, "of" means multiplication or product

Thus $ 2772 is paid in state income tax
