Answer:
105 + 120 = 225 I hope this answer is right
the answer would be 60°,75° and 45°
Step-by-step explanation:
Firstly,
On producing the base BC to XY, the angle ACY is 120° , so
angle ACB = 180°-120°= 60°
Similarly Angle ABC = 180°-105°= 75°
Finally using angle sum property,
ACB+ABC+BAC= 180°
60°+ 85°+ BAC= 180°
BAC= 180°-60°-75° = 180°- 135° = 45°
