Answer:
y=-8
Step-by-step explanation:
First find the slope which is rise over run which equals (y2-y1)/(x2-x1)
(-8-(-8))/(9-(-2))
(-8+8)/(9+2)
0/11
slope = 0
Now you have the slope of 0. You can plug in one of the given point (x,y) to find b
-8=0(9)+b
-8=b
Combine everything
y=0x-8
x = 210
The opposite arc is always twice the angle.
so 105 * 2 = 210.
factorise out a and x :
but from general factorization:
a » x
b » 2
therefore:
