Answer 1

Answer:

b) 77°

∠PAB = ∠ABC = 50°

By alternates interior angle

∠ACS = ∠ABC+ ∠BAC

because

Exterior angle = Sum of opposite interior angle

127° = 50° + ∠BAC

127° - 50° = ∠BAC

77° = ∠BAC

I hope it's help you please mark me as brainlist please I need it.

Answer 2

Answer:

B

Step-by-step explanation:

Angle ACS is 127°

A straight line is 180°.

So, 180° - 127° = 53°

Angle ACB is 53°

Angle ABC is 50° because it is an alternate angle.

53° + 50° = 103°

180° - 103° = 77°

Final answer : Angle BAC is 77° [B]
