The angle 1 could be simply find by the straight line angle theorm
125°+1=180
1=180°-125°=55°
Similarly
as angle 1 =55°[as we find above]
Also the angle C=180°-125°=55°[linear pair]
Also
The
A+B+C=180°[angle sum property]
55°+55°+A=180°
A=70°
So
A+2=180°
2=180°-70°
2=110°

Answer:
angle1 = 55°..... and angle2= 110°
Step-by-step explanation:
From the figure,
Angle1 + 125° = 180° (By linear pair)
Angle1 = 180-125
Angle1 = 55°
Therefore, Angle1 = 55°
From the figure,
AngleACB + 125° = 180° (LINEAR PAIR)
ANGLE ACB = 180-125 = 55°
NOW WE HAVE TWO ANGLES ... ANGLE ABC and ANGLE ACB....
Therefore,
angleACB + angleABC = angle 2 (Exterior angle)
angle2 = 55 + 55
angle2 = 110°
Therefore, Angle2 = 110°
