                Hi! Can someone please help me with these? Thanks! :)
Directions: Look for the direction angle for vector v. If necessary, round your answer to the nearest tenth of a degree.
 
1.) v = 8i - 10j
2.) w = -4i - 3j

    #1
tanθ = -10/8 = -1.25
θ = -51.3° or 308.7°
Do #2 the same way. Make sure you end up in the right quadrant.
