Question 146806: Let A = (0,0), B = (4,2), C = (1,3), find the exact size of angle CAB. Justify your answer without your protractor. Answer by Alan3354(69443) (Show Source):
You can put this solution on YOUR website! The angle from the x-axis to AC is the arctan(3), and AB is the arctan(0.5).
Subtracting gives 45 degrees.
