Answer part B please. Show all work.
![1. Consider the vector v =< 0,- 5 > in the coordinate plane with its tail at the origin.
a.
Find the angle 0 between v =< 0,- 5 > and w = < 2,7 >. Assume 0° < 0 < 180°. Give your
answer correct to three decimal places.
b. Another vector r, with the same length as v =< 0, - 5 >, can be found such that the angle between
vectors v andris 100°. Determine all possibilities for this second vector. Give your answer(s) in the
< x, y >, where x and y are correct to three decimal places.
