let the name of the angle be x.

the equation will be .....

                       

                                  0 =2(180-x)-12
                                  0 =360-2x-12
                                 +2x    +2x     
                                  2x=360-12
                                  2x=348
                                  
                                 2x/2=348/2
                                    x=174
