Answer and Step-by-step explanation:







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!!
I believe it’s the last answer. Rotation of 180 degrees clockwise with a dilation of 5.
