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 :)
