The answer is D (60 degrees) and I understand how to get that answer. But this assumes that the new velocity's component of v/4 can form right angles with another component of the new velocity.

So I'm confused whether vector components always form right angles to each other. When I searched this up, I have seen vector diagrams with components that do not form right angles to each other.
