A map suggests that Atlanta is d1 = 729 mi in a direction of ?1 = 5.05° north of east from Dallas. The same map shows that Chicago is d2 = 562 miles in a direction of ?2 = 21.0° west of north from Atlanta. Modeling the Earth as flat, use this information to find the displacement from Dallas to Chicago.
(a) find the magnitude.
(b) find the direction north of east of Dallas.
