The Greatest Common Factor (GCF) is the largest number that will be divided evenly into that number. For example, for 24, the GCF is 12. For a polynomial, the GCF is the largest polynomial<span> that will divide evenly into that polynomial.</span>
The formula for the total sum of the inner angles of the polygon is
Sn= (n-2) 180°
1) S6= (6-2) 180 = 4*180 = 720° In the hexagon all angles are equal
α= S6/6= 720/6= 120°
2) In each polygon the sum of the external angles is 360°
3) S5= (5-2) 180 = 540° than we can add up all angles
x+131+108+107+110=540 => x= 540-456= 84°
4) α = 360/5=72°
Good luck!!!
Yes, the decimal form of 
is indeed a repeating decimal. The expression is equivalent to 
, which is also 1.3333333 or "1.3 bar", signifying that the 3 will repeat infinitely.
You would start on x(x being the 2 digit number)and to multiply it by 20 you would move to the right x amount of spaces repeating this process 20 times.
