Answer:

/_ ABC = 35°

Step-by-step explanation:

Let the 80 degree angle be angle AQM

Then,

angle AQM' = 180 - 80          (M' is the other end of M)

                    = 100°          

angle CAB = AQM'                 (Corresponding Angles)

=> angle CAB = 100°

Now,

angle CAB + ACB + ABC = 180°      (Angle-Sum Property)

=> 45 + 100 + ABC = 180°

=> ABC = 35°

Hope it helps :)
