Answer 2

Answer:

no. of sides = 8

Step-by-step explanation:

each interior angle = 3$\pi$/ 4

                               =  3 × 180°/4

                              =    3 × 45°

                               =    135°

   sum of all interior angles = 135°n        [ n = no. of sides ]                  

           135° n =  (n-2) × 180°

           135° n  = 180° n - 360°

           135°n - 180° n = -360°

            - 45° n  =  - 360°

              n   =  -360° / - 45°

              n  =   8

∴ no. of sides = 8
