Question

question num 7 please solve it

Answer 1

Exterior angle of any polygon adds upto 360 degrees

Regular polygons are equilateral and equiangular

thus if a y times 80 is 360 then it is divisible

80 X 3 = 240

80 X 4 = 320

80 X 5 = 400

Therefore a regular polygon cannot have each side as 80 degrees as 360 is not divisible by 80
