In the diagram, shown below:
If ∠ABC = 60°and ∠DAB = 127°
Then what is ∠ACB ?

Answer:
Angle ACB = 67
Step-by-step explanation:
Angle DAB and BAC are supplementary angles. This means they add up to 180 degrees. So subtract 127 from 180 to find angle BAC which is 53. We know that a triangle's degrees add up to 180. So take 180 and subtract (60+ 53) to find angle ACB.
