Step-by-step explanation:

no. of sides = ?

interior angle = 168°

we know,

Each Interior angle of regular polygon = (n-2) ×180÷n

                                                           168 = 180n-360÷n

                                                          168n = 180n-360

                                                            360 = 180n-168n

                                                            360 = 12n

                                                         360÷12 = n

                                                             30 = n

Therefore, number of sides of regular polygon(n) = 30
