please answer fast and with complete explanation​

Answer 1

Answer:

60 degree

Step-by-step explanation:

angle ABC=120+x=180 degree

                x=180-120

                x=60 degree

angle ACB=120+x=180 degree

                x=180-120

                x=60 degree

Angle A=60+60+x=180 (ASP of triangle)

            =120+x=180

         x=180-120

         x=60 degree

Hence, angle A=60 degree
