Answer:
Step-by-step explanation:
if (x,y)is mid point of two points (x1,y1) ,(x2,y2) then
x=(x1+x2)/2
and y=(y1+y2)/2
coordinates of M are ((-2+(-8))/2,(-7+7)/2)
or are (-5,0)
Answer:
-8
Step-by-step explanation:
-31 and +31 cancel each other out leaving you with -8
Find the sum of the interior angles of a 22-gon. Since the polygon has 22 sides, we can substitute this number for n: (n 2)180˚= (22 2)180˚= 20180˚= 3600˚. Each angle of a regular polygon measures 157.5˚.
