I actually didn't think this unit was easy, but I got a 100 without Mitesser moolah so I guess I understood it. I really had a hard time picturing the vectors but I eventually learnt to just draw everything like a triangle. I wish I could do this well at every section!
2b. I could not for the life of me picture this. It took like 5 minutes to draw the thing.
tanx= 2.24/4
x= 29.25 degrees
4. 120cos35+0+80cos120= 58.3N
120sin35+60+80sin120= 198.11N
58.3 sq. + 198.11 sq. = c squared
12,646.46= c squared
c= 206.51N
