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!

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