Answer:

pls attach figure also otherwise you can't get a correct answer

Answer 2

Answer:

Side BC of triangle ABC is produced to D.

∴∠ACD=∠A+∠B [Exterior angle property]⇒128°=∠A+43°⇒∠A=(128−43)°⇒∠A=85°⇒∠BAC=85°

Also, in triangle ABC,

∠BAC+∠ABC+∠ACB=180° [Sum of the angles of a triangle]⇒85°+43°+∠ACB=180°⇒128°+∠ACB=180°⇒∠ACB=52°
