    I just started applied Maths and the very first question I try I not sure if I'm doing it right.

    Add a and b in each case, denoting your answer a+b :
    And then you given 5 different angles, each vector labeled a or b.

    I'm pretty sure I just have to show the a+b vector.

    Any advice is appreciated.
    Thanks

    Hi there. I'm afraid your post doesn't make any sense (to me anyway). Can you post up the question EXACTLY as it's asked in the book and then we'll help you.

    You haven't really been given an "angle", I'd say. You've been given two vectors, labelled a and b, which have probably either been placed "tip to toe" or "toe to toe".

    You can add them using the "triangle rule" or the "parallelogram rule".

    This might help:
