Answer:
18 sides
Step-by-step explanation:
with regular polygons it is best to remember that:
(1) all the EXTERIOR angles add up to 3600
(2) 1 exterior angle+1 interior angle =1800
Work with the exterior angles. In this case:
1 int. <=180−160=200
No. of sides =36020=18
Answer:
The answer would be option A. h = –7, h = 21
Step-by-step explanation:
Question: -2 |h-7|=-28
Substitution: -2 |-14 (-7-7)| = -28
-2*14=-28
Substitution 2:
-2 |14 (21-7)|=-28
-2*14=-28
Answer:
4 and 5 can make this true.
