The sum of all angles in an octagon is given by

180*(n-2) >>>>>>>>>with n = 8

180*(8-2) = 1080 degrees

A + B = 1080 .......where

A is the <span>angle of an octagon which is twice that of the other seven angles
</span><span>
B equals the sum of the other seven angles

If we assume each angle of B is equal to each other, then

B = x+x+x+x+x+x+x = 7x
</span>
And A = 2x

The equation that results is

A + B = 2x +7x = 9x =1080

x = 120 degrees
2x = A = 240 degrees

What is the equivalent expression for 2x + 8y

klio [65]

If this helps you consider making it brainliest as it helps me out.

2(x+4y) is the equivalent expression.

Let’s say x = 1 and y = 2

Then 2x + 8y would be 18

Same thing for 2(x+4y)

Hope this helps!

Help!!! Find the center and radius of the circle with the equation (x-4)²+(y+6)²=16

WITCHER [35]

Answer:

Center: $(4,-6)$

Radius: $4$

Step-by-step explanation:

It is necessary to remember that the Equation of the circle in Center-radius form, is:

$(x -h)^2 + (y-k)^2 = r^2$

Where the center of the circle is at the point (h, k) and the radius is "r".

Then, given the following equation of the circle:

$(x-4)^2+(y+6)^2=16$

We can notice that it is written in Center-radius form. Then we can identify that:

$h=4\\k=-6$

Therefore the center is:

$(4,-6)$

And the radius is:

$r^2=16\\\\r=\sqrt{16}\\\\r=4$
