Answer 2

Answer: hey mate...

ANGLE SUM OF A CIRCLE =360 DEGREE

Step-by-step explanation: x=30=360

                                        X=360-30=330

                                           THEREFORE 330 DIVIDED BY 30

                                          =11

                                       (the 1 shown in the qn wasnt included)

                                              thus....  11+1=12

12  SUCH PARTS ARE NEEDED TO COMPLETE A CIRCLE.......
