Answer:

140 degree

Step-by-step explanation:

The sum of the interior angle measures in a regular polygon is 1260 degree.

(n-2)*180=1260

180n-360=1260

180n=1260+360

180n=1620

n=1620/180

n=9

Now, evaluate the measure of one of the interior angles of the polygon.

((9-2)*180)/9=140 degree.

Solve the following system of equations and show all work. <br><br> y = -x^2 + 4<br> y = 2x + 1
Pavel [41]
-x^2 + 4 = 2x + 1
-x^2 - 2x + 4 - 1 = 0
-x^2 - 2x + 3 = 0
(x + 3)(-x + 1)= 0

x + 3 = 0           -x + 1 = 0
x = -3                -x = -1
                          x = 1

so x = -3 and x = 1

the size of the second application is 3.45 MB less than he first application. What is the size of the second application
mr_godi [17]

The size of the second application given the size of the first application and the expression ( x - 3.45 mb) for the size of the second application is 293.55 MB.

<h3>Equation</h3>

Let

  • Size of the first application = x

  • Size of the second application= x - 3.45 mb

For instance,

if the size of the first application is 297 MB

Size of the second application= x - 3.45 mb

= 297 MB - 3.45 MB

= 293.55 MB

Therefore, the size of the second application given the size of the first application and the expression for the size of the second application is 293.55 MB
