Hello, I am having some trouble with this question:
A map suggests that Atlanta is 731 mi in a direction of 4.90° north of east from Dallas. The same map shows that Chicago is 561 miles in a direction of 21.1° west of north from Atlanta. Modeling the Earth as flat, use this information to find the displacement from Dallas to Chicago.
Here's what I did:
731cos(4.90)= 728
731sin(4.90)= 62.4
728+62.4= 790.4
561cos21.1= 523
561sin21.1= 202
523+202= 725
790.4+725= 1515.4 miles<----- magnitude of displacement
I have no idea if I am doing it right...
