Angle between vectors

Find the angle between the given vectors to the nearest tenth degree. u = (6, 22) and v = (10, -11)

Correct answer:

A =  0 °

Step-by-step explanation:

u=62+222=2 13022.8035 v=102+(11)2=22114.8661 s=(6) (10)+(22) (11)=182 A=π180°arccos(s/(u v))=π180°arccos((182)/(22.8035 14.8661))122.4712=0
