Step-by-step explanation:
Given that,
Angle ACB = 55°
Angle ADE = 65°
Angle ACB= Angle AED (Corresponding angles)
Angle AED = 55°
Now,
ADE is a small traingle
Angle ADE + Angle AED + Angle DAE = 180°
65° + 55° + Angle A = 180°
Angle A = 180° - 120°
Angle A = 60°
Now,
In Triangle ABC,
Angle A + Angle B + Angle C = 180°
60° + Angle B + 55° = 180°
Angle B + 115° = 180°
Angle B = 180° - 115°
Angle B = 65°
