im not sure how to do this question

80 N and 60 N force act concurrently on a point. find magnitude of the vector sum if the forces pull
-in the same direction
-in opposite direct.
-at right angles to each other

thanks

    i don't understand..

    do u use cos and sin?

    i don't understand the question.

    You don't need to use cosines and sines for this. If the forces are in the same direction, that add. If they are in opposite directions, subtract one from the other. If they are at right angles, use the Pythagorean theorem
