I solved it and got a completely wrong answer. the N 30 W means angle 30 is closer to the north direction.

How would you add all the vectors together at once? just using the dx method? so dx=25cos30E+30cos40W+35cos65E and dy=25sin20N+30sin40N+35sin65S But then how would you use the c2=a2+b2?

D1 & D2 dx=25cos30 = 21.65 w+22.98 E = 1.33 E dy=26sin30+30sin40= 12.5 N+19.28 N = 31.78 N c^2=a^2+b^2 C=31.8 m tan= 1.33/31.78 =2.41 therefore, 31.8 m [N 2.4 E] D1 & D3 dx=25cos60W+35cos65W =27.3 W Dy=25sin60N+35sin65[s]=10.07 S C2=27.32+10.072= 29.1 m Tan= 27.3/10.07 =69.75...

I did that and I got the wrong answer?

Homework Statement Use the component method to add the following displacement vectors. D1= 25 m [N 30 W], D2= 30 m [N 40 E], D3= 35 m [S 25 W] Homework Equations I know all of the equations for vx, vy and the five equations. I also know sin, cos, tan and velocity, displacement...

Thank you so much!
