The sum of the interior angles of a polygon is 1080 degrees. How many sides does the polygon have?

postnew [5]

9514 1404 393

Answer:

Step-by-step explanation:

The formula for the number of degrees in the sum of the interior angles of an n-sided polygon is ...

sum of angles = 180°(n -2)

Filling in the given value and solving for n, we get ...

1080 = 180(n -2)

6 = n -2 . . . . . . divide by 180

8 = n . . . . . . . . add 2

The polygon has 8 sides.

The marker cost 1/3 as a pen.The pen cost 1/3 as much as the book.The book cost 1/3 as much as the game. The price of the marker

creativ13 [48]

Let the price of game, marker, pen and book be $w, x, y and z.

$x = \frac{1}{3} y$
$y = \frac{1}{3} z$
$z = \frac{1}{3} w$
$x = \frac{1}{3} y \\ x = \frac{1}{3} ( \frac{1}{ 3} z) \\ x = \frac{1}{3} ( \frac{1}{3} ( \frac{1}{3} w) \\ x = \frac{1}{27} w$

How to solvee ????? PPLLEASEEEEE

Kipish [7]

If they are all in a line then we can find the equation of their line using: y = mx + b

First find m using points (2,5) and (3,3)

m = (5-3)/(2-3) = 2/-1 = -2

Now using (3,3) and m= -2 to solve for b:

3 = -2(3) + b
3 = -6 + b
9 = b

So our equation is y = -2x + 9
That is the solution for question b)

Now to find the mystery point, solve:

1 = -2x + 9
-8 = -2x
4 = x

So our mystery point is (4,1)

So for part a) the answer is k = 4
