Please help me with this problem in the picture, its about trigonometry.

Answer:
Step-by-step explanation:
The value of a vector is the difference between its terminal point and its initial point:
u = P2 -P1 = (6-8, 5-3) = (-2, 2)
v = P4 -P3 = (9-11, 10-8) = (-2, 2)
Vectors u and v are both (-2, 2), so are equivalent vectors.
