Step-by-step explanation:
let interior angle be = x
exterior angle will be =( 1/3)×x = x/3
now
interior angle + exterior angle = 180 (Libera pair angles)
x + x/3 = 180
(3x/3)+ (x+3) = 180
(3x +x)/3 = 180
4x = 180×3 = 240
4x = 240
x = 540/4 = 135
now
exterior angle = X/3 = 135/3 = 45
number of side of polygon = 360/exterior angle
number of side of polygon = 360/45 = 8 sides
sorry for editing answer .
