the answer is very simple 12 sides---------------------------------------------------------------- Here you go for the rule
--------------------------
Each interior angle in a regular polygon = (n-2)×180 ÷ n** n = number of sidesI love algebra so i solved with it(n-2)×180÷n = 150(n-2) × 180 = 150 × n180 n × -360 = 150 n180 n - 150 n = 36030 n = 360n = 360 ÷ 30n = ...............
