Answer:

Step-by-step explanation:
Given:
The magnitude, v=12
The angle
it makes with the positive x-axis =
Now for a vector (x,y)
; and
Therefore:


Similarly:


Recall that:

Therefore: 
The vector in the form ai+bj is therefore:

<em>Depending on what you trying to say...
</em>
Six times a length (w) is 6w
or
Six times a length is w, is 6l=w
<em>But I can't tell because of the typo
</em>
Hope this helps!
