Question 744212
Two cars approach a right-angled intersection, one traveling south at 40 km/h
 and the other west at 70 km/h. 
When the faster car is 4 km from the intersection and the other car is 3 km
 from the intersection, what is the angle formed between the 2 cars?
:
I may be missing something here, but won't the angle between the two cars
 always be 90 degrees, if one continues going south and the other west??
