Answer:
(B) The magnitude is 7sqrt2, and the direction angle is approximately 135 degrees.
Step-by-step explanation:
From the figure, the coordinate of the tail of the vector,

The coordinate of the head of the vector,

The magnitude of a vector is the length between the head and tail of the vector.
By using the distance formula,
the magnitude of the vector 

Now, let
be the angle made by the vector with the positive direction of the x-axis, so

So, the magnitude of the vector is
which makes
with the positive direction of the x-axis.
Hence, option (B) is correct.
