Use the component method to add the vectors and shown in the figure. The length of is 2.55 m and the angle θ = 31.5°. Express the resultant + in unit-vector notation.
The answer should be in the form of ...i + ...j
so far i have done
3*cos(31.5) = 2.56 so this is for ...i but I am...

For part (c) I chose a grid point on the line far from the origin: slope = 0.31 g/600 cm2 = 0.000 52
For part (b) I did (200, 0.1) (300, 0.15).
Then (0.15-0.1)/(300-200) = 5* 10^-4 * 100 *100 = 5%
The answer for part c is The answer to part c is 0.00052 g/cm^3
would someone please kindly tell me the answer to part b.
im really stuck.
help is most appreciated
Thank you
