I have been working on homework and cant seem to grasp the right order or equation movements in.
AN example of a question would be
SOlve for both FB and FA using substitution
Given:
-FA cos(35) + FB cos(75)=0
-FA sin(35) +FB sin(75)= 235.4
Any help would be appreciated
THis is my work
-FA cos(35) +FBcos(75)=0
FB=FAcos(35)/cos(75)
substitute
-FAsin(35)+(FAcos(35)/cos(75))sin(75)=235.4
and then whatever i try seems to make no sense after that. I may be missing a rule or something but if any have explanations that would be awesome.
