Once upon a time,on a piece of paper Alice drew a vector 20cm long at 37 degree north of east. Next, Alice drew a vector 8.5cm long at 45 degree north of west, with the tail of this vector at the head of the previous vector. Finally, Alice drew a vector with a tail at the tail of her first vector and a head at the head of her second vector. I) how long is Alice's third vector? ii) What is the direction of Alice's third vector?
