Answer 2

Answer:

         The value is 51.4° (Option C).

Step-by-step explanation:

         The ant repeats the two steps 7 times and the ant makes 1 complete revolution.

              1 complete revolution = 360°

               Number of steps taken = 7

               Each angle A  =360°/7

                                       =51.429

                                        =51.4°  ( upto one decimal place).
