Answer
We can sketch the vector $u$ and the vector $v$ so that their initial points coincide with an angle of $\theta = 30^{\circ}$ between the two vectors. When we complete the parallelogram, the resultant is the vector through the middle of the parallelogram.
Work Step by Step
$\vert u \vert = 20$
$\vert v \vert = 30$
$\theta = 30^{\circ}$
To sketch the resultant, we can sketch the vector $u$ and the vector $v$ so that their initial points coincide with an angle of $\theta = 30^{\circ}$ between the two vectors. Then we can use another copy of the vector $u$ and the vector $v$ to complete the parallelogram. The resultant is the vector through the middle of the parallelogram.
