If two vectors have the same magnitude and direction, but their degrees do not add up to 90°, are they equal?
In my physics book, it stated that if two vectors have the same magnitude and direction then they are equal, but on a sample question, the answer was that two vectors with 100m and 30°/60° (in the same direction) are equal.
My question is are they equal only because they add up to 90° and are in the same direction, or are they equal just because they are in the same direction and the 90° was simply a coincidence.

Equal vectors means they have the same magnitude and direction. If those vectors had different directions, they can't be considered equal. They are equal in magnitude, but not equal.
I don't know what "30°/60° (in the same direction)" means. Those are two different numbers, so they aren't the same direction.
