Problem 3.2 part a draw the vector c⃗ =a⃗ +b⃗ .(figure 1)

I can't answer this question without a figure. I've found a similar problem as shown in the first picture attached. When adding vectors, you don't have to add the magnitudes only, because vectors also have to factor in the directions. To find the resultant vector C, connect the end tails of the individual vectors. The red line (second picture) represents the vector C.
