Answer:
A: 0 degrees
Step-by-step explanation:
(-2,3) and (-6,9) have the same slope and are both located in the second quadrant.
The angle between given vectors is 0°. So, option A is correct.
Important information:
- The given vertors are u = (-2, 3) and v = (-6, 9).
Angle between two vectors:
Two vectors [tex]v_1[/tex] and [tex]v_2[/tex] are parallel if:
[tex]v_1=kv_2[/tex]
Where, k is a constant.
[tex]3u=3\times (-2,3)[/tex]
[tex]3u=(3\times (-2),3\times 3)[/tex]
[tex]3u=(-6,9)[/tex]
[tex]3u=v[/tex]
It means u and v are parallel vectors and the angle between parallel vectors is always 0.
Therefore, the correct option is A.
