Number of angles = number of sides
180 - 120 = 60 (calculating the exterior angle)
360 / 60 = 6
There are 6 sides.
Hope this helps! :)

Answer:
Step-by-step explanation:
The line has a slope of -1/3. For lines to be perpendicular there product must equal negative 1
m1(m2)=-1
-m/3=-1
m=3
So we know our line has a slope of three so
y=3x+b, we can solve for the y intercept, b, using point (-2,8)
8=3(-2)+b
8=-6+b
b=14, so our line is
y=3x+14
