Answer:
option B
Step-by-step explanation:
Sum of interior angles of a polygon with n sides:
![[ \ because \ straight \ line \ angle = 180^\circ \ ]](https://tex.z-dn.net/?f=%5B%20%5C%20because%20%5C%20straight%20%5C%20line%20%5C%20angle%20%3D%20180%5E%5Ccirc%20%5C%20%5D)
That is ,
OR
Sum of exterior angles of a regular polygon = 360
Given 1 exterior angle of the regular polygon is 40
Therefore ,
Answer:
7/10
Step-by-step explanation:
0.7+0.07+0.007=0.777
fraction=777/1000
simplest form: 777/1000=7/10
srry if im wrong

Answer:
90
Step-by-step explanation:
<em>Hey there!</em>
Well 90.000 to the nearest tenth is just 90 because there is no decimal places to round.

This breaks into two inequalities:
2x - 3 > 6
and
-2x + 3 > 6
------------------------
2x - 3 > 6
Add 3 to both sides:
2x > 9
Divide 2 to both sides:
x > 4.5
-----------------------
-2x + 3 > 6
Subtract 3 to both sides:
-2x > 3
Divide -2 to both sides:
x < -1.5
The equation of a circle is written as ( x-h)^2 + (y-k)^2 = r^2
h and k is the center point of the circle and r is the radius.
In the given equation (x+3)^2 + (y-1)^2 = 81
h = -3
k = 1
r^2 = 81
Take the square root of both sides:
r = 9
The center is (-3,1) and the radius is 9
