1. The problem statement, all variables and given/known data For distant objects, the angular size in degrees can be approximated as 57° (w/d), where w is the width of the object and d is its distance. What is the angular size of the headlights on a car 13 km away if the headlights are 1.5 m apart? 2. Relevant equations D/w 3. The attempt at a solution 13 km to m = 13000 m. 1.5 m / 13000 m = 1.15E-4. This answer was incorrect and I'm trying to figure out what I'm doing wrong. Any help would be really nice, thanks!
