Answer:
5
Step-by-step explanation:
Plug in the given x- and y-coordinates (in this case we'll use 
for the missing variable)
Simplify
Subtract 18 from both sides (Subtraction Property of Equality)
Step-by-step explanation:
(n-2)×180=3420
180n-360=3420
180n=3420+360
180n=3780
n=3780/180
n=21
that is, the number of sides is 21
to get the size of each exterior angle=
360/21
=17.14°
