she is going west at 6

Draw a vector north (up) 8 units long.

At the tip of that, the north end, draw a vector west(left) 6 units long.

Add those two vectors by drawing the hypotenuse from lower right to upper left.

Find the length of that hypotenuse.

That is the magnitude of your resultant velocity.

The angle the hypotenuse makes with the north vector at its base is the angle west of north of the resultant vector. Its tangent is 6/8 or 3/4
