i think this because to work ou the sum of interior angles you do (n-2)x180 10-2=8 and 8x 180= 1440 1440/10= 144 so the shape must have 10 sides.

if the exterior anglr and the interior angle add up to 180°; then the external angle is 36°. all exterior angles in a polygon add to 360° so 360 divided by 36 equals 10 which means there are 10 sides.
