Answer:
1.31
Step-by-step explanation:
I would but i dont have a graph
a. distance around the circle
13.
<3 = 180 - <1
<3 = 180 - 90
<3 = 90°
14.
<8 = 180 - <6
<8 = 180 - 137
<8 = 43°
15.
<4 = 180 - <2
<4 = 180 - 34
<4 = 146°
y=-x
Plug (-2,2) for y= mx+b (2=m(-2) + b)
Plug (2,-2) for y=mx +b (-2=m(2) +b)
Causing them to turn into a system of equations for y= -x
