North is the direction of positive y-axis. East is the direction of positive x-axis. So West will be the direction of negative x-axis.
Northwest will mean, in between north and west i.e. in between y-axis and the negative x-axis which is the mid of the 2nd quadrant. Thus the vector pointing northwest will form an angle of 135 degrees with positive x-axis.
The magnitude of unit vector is 1 and is forming an angle of 135 degrees. In terms of its components, we can write:
x-component = 1 cos (135) =
y-component = 1 sin (135) =
Thus the unit vector will be =
In vector form, component form the vector can be written as:

Answer:
68
Step-by-step explanation:
For angle A, 3 is the adjacent leg. 8 is the hypotenuse.
The trig ratio that relates the adjacent leg to the hypotenuse is the cosine.
We know the cosine of angle A equals 0.375. We take the inverse cosine of 0.375 to find the measure of the angle.
