Every added angle to a polygon adds another 180 degrees to the sum of the angles. The starting point is 180 degrees for a triangle (n=3). So the general formula is 180*(n-2). Fill in n=3 to test if 180 comes out, it does!!

Answer:
fog =gofthen it will be equal
so initially the paper is in full piece.
it is cut into half, which makes into 2. this is pattern 1.
then the halves is further divided in to 2.
then the total becomes 4. then the four pieces are cut into halves, which makes the total of 8 pieces, that is pattern 3..
is if we see the pattern it is a geometric progression.
Tn=ar²-¹ where the r is common ratio
and a is the first term. the question mentioned repeat 15 times.
1. 2
2. 4
3. 8
4. 16
4÷2=2 the common ratio.
So T(15)= 2×2¹⁵-¹
2×2¹⁴
2¹⁵
32768 pieces
please mark brainliest.
