Vector Aarrowbold points in the negative y direction and has a magnitude of 8 units. Vector Barrowbold has the same the magnitude and points in the positive x direction. Find the direction and magnitude of the following vectors.


a) Aarrowbold + Barrowbold
magnitude
direction ° (counterclockwise from the +x axis)

(b) Aarrowbold − Barrowbold
magnitude
direction ° (counterclockwise from the +x axis)

(c) Barrowbold − Aarrowbold
magnitude
direction ° (counterclockwise from the +x axis)


I need a solution/steps to solve this. thanks!

    (a)A+B= sqrt(A²+B²)
    45º counterclockwise from the +x axis
    (b)
    A-B= sqrt(A²+B²)
    135 ºcounterclockwise from the +x axis
    (c)
    B-A= sqrt(A²+B²)
    315°(counterclockwise from the +x axis)
