1. The direction of the vector relative to the positive x-axis satisfies
2. A vector with magnitude and direction has component form
We have , but "angle of 60 degrees with the negative x-axis" is a bit ambiguous. I would take it to mean "60 degrees counterclockwise relative to the negative x-axis", so that the direction is . Then
But this doesn't match any of the options, so more likely it means the angle is 60 degrees clockwise relative to the negative x-axis, in which case and we'd get
3. Same as question 2, but now we're using notation. The vector has magnitude and its direction is . So the vector is
4. The velocity of the plane relative to the air, is 175 mph at 40 degrees above the positive x-axis. The velocity of the air relative to the ground, , is 35 mph at 60 degrees above the positive x-axis. We want to know the velocity of the plane relative to the ground, .
We use the relationship
Translating the known vectors into component form, we have
This vector has magnitude and direction
(or 43 degrees NE)

Answer with Step-by-step explanation:
Relationship between rotation and reflection:
In reflection, the pre-image gets flips across the same line.
whereas in rotation, the pre-image get spin around a point.
Rotations can be represented as two reflections i.e. the composition of reflections over two intersecting lines is always equal to rotation of that object.
In rotation, the object will get turned, this is turning some degree either clockwise or anti-clockwise.
Hence, rotation requires spinning and reflection requires flipping.
