Answer:
900 degrees
Step-by-step explanation:
Use the formula for interior angles
Sum = (n - 2) x 180
Sum = (7 - 2) x 180
Sum = 5 x 180
Sum = 900 degrees

The center is at origin O(0,0).
If it contains the point, P(-8,6), then the radius r is, by Pythagoras theorem,
r=sqrt((-8)^2+6^2)=10
The general equation of a circle at centre (xc,yc) with radius r is given by
(x-xc)^2+(y-yc)^2=r^2
Substituting r=10, (xc,yc)=(0,0)
the resulting equation is therefore
(x-0)^2+(y-0)^2=10^2
or simply
x^2+y^2=100

Answer: 107
Step-by-step explanation:
1 Remove parentheses.
16x-80<2716x−80<27
2 Add 8080 to both sides.
16x<27+8016x<27+80
3 Simplify 27+8027+80 to 107107.
16x<10716x<107
4 Divide both sides by 1616.
x<\frac{107}{16}x<

Since you know the x and y values, you just have to plug these into the linear slope-intercept equation:
y = mx + b
-10 = m(1) + b
m + b = -10
b = -10 - m
Now that we have a value for b, we can plug this into the other equation:
8 = m(-8) + b
8 = -8m + (-10 - m)
8 = -9m -10
18 = -9m
m = -2
Now that we know what m is equal to, we can plug this into our first equation to get an answer for b:
b = -10 - m
b = -10 -(-2)
b = -10 + 2
b = -8
Our final equation is y = -2x - 8
