Answer 1

∠ PAB = ∠ ABC ( Alt. int. angles are equal )

So, ∠ ABC = 50°

now, ∠ ACB = 180° - ACS ( Linear pair )

∠ ACB = 180° - 127°

∠ ACB = 53°

now,

∠ ABC + ∠ ACB + ∠ BAC = 180° ( Angle sum property )

50° + 53° + ∠ BAC = 180°

103° + ∠ BAC = 180°

∠ BAC = 180° - 103

∠ BAC = 77°

Final Answer

∠ ABC = 50°

∠ BAC = 77°

Answer 2

Angle BAC=77 and angle ABC=50
