Question

Help please thank u :(

Answer 1

We know that :

⊕  Sum of the three angles in a triangle should be equal to 180°

Given : Angle BAC = 50° and Angle ABC = 75°

⇒  Angle BAC + Angle ABC + Angle ACB = 180°

⇒  50° + 75° + Angle ACB = 180°

⇒  125° + Angle ACB = 180°

⇒  Angle ACB = 180° - 125°

⇒  Angle ACB = 55°
