B, that makes the six negative and not the five
The exterior angles = 180 - 157.5 = 22.5 degrees
the exterior angles of all polygons add up to 360 degrees
therefore the total number of sides n = 360 / 22.5 = 16
The correct answer is B
325-45=280
8x35=280
Y=2.5 and if u need me to explain i will be glad to
