Answer 1

Answer: PLS MARK ME BRAINLIEST

 ∠BAC = 40°       &       ∠CAS = 130°  

Explanation:

In ΔABC

∠BAS = ∠CBA = 90°             (BA ⊥ RS)

now,

 ∠CBA + ∠BAC + ∠ACB = 180°         {sum of all angles of traingles is 180°}

 90° + ∠BAC + 50° = 180°

 ∠BAC = 180° - 140°

 ∠BAC = 40°

∠CAS = ∠BAC + ∠BAS

∠CAS = 40° + 90°

∠CAS = 130°
