Answer:
A (10, -9)
B (0,-9)
C (0,-1)
D (10,-1)
Step-by-step explanation:
Negate the x-coordinates of each of the vertices
Answer:
57°
Step-by-step explanation:
Let's assume the measurement of the second angle is x.
so, following the problem
(2x + 9) + x = 180
2x + x = 3x
=> 3x + 9 = 180
=> 3x = 180 - 9
3x = 171
x = 171/3
x = 57°
57° is the smallest angle
Answer:
Step-by-step explanation:
a)
the sum of all angles in a quadrilateral must be 360º
y+88+25+35 = 360
y = 360=88-25-35
y = 212º
b)
the sum of all angles in an octagon must be 1080º
45+45+140+140+6y = 1080
6y = 1080-90-280
6y = 710
y = 710/6
y=~ 118,3º

I hope my answer has come to your help. God bless and have a nice day ahead!
I think it's A. I can't really see the graphs clearly. It's the one that crosses at (15,2)
