Answer: Given , tan 2A=cot(A-18°)

                         tan 2A=cot(90°-2A)

                         cot (A-18°)=cot(90°-2A)

                                 A-18°=90°-2A

                                 A+2A=90°+18°

                                    3A=108°

                                     A=108°/3

                                       A=36°
