Answer:
Sum of angles of a polygon with one side less = (12-2)x180 = 1800
Sum of angles of a polygon with one side more = (14-2)x180 = 2160
Step-by-step explanation:
(n-2)x180 = 1980
n = 13
Sum of angles of a polygon with one side less = (12-2)x180 = 1800
Sum of angles of a polygon with one side more = (14-2)x180 = 2160
First calculate (-8x-15)=120
Then multiply - 11x120
=-1320
1/6d + 2/3 = 1/4(d - 2)
1/6d + 2/3 = 1/4d -1/2
2/12d + 4/6 = 3/12d -3/6
4/6 = 1/12d - 3/6
7/6 = 1/12d
7/6 x 12/1 = d
84/6 = d
14 = d
So d = 14.
Hope I helped.. ^^
3.12 (repeating) = 3 12/99 reduces to 3 4/33 or 103/33
if there is one number repeating, like 0.222...u put that one number over 9...making it 2/9.
if there is 2 numbers repeating, like 0.1313...u put the two repeating numbers over 99...making it 13/99
if there are 3 numbers repeating, like 0.123123...u put ur three repeating numbers over 999...making it 123/999
