Find the

Find the magnitude of the angle between two vectors u = (3; -5) and v = (10; 6)

Correct answer:

A =  28.0725 °

Step-by-step explanation:

u=(3,5)=(3,5) v=(10,6)=(10,6)  s=ux vx+uy vy=3 10+5 6=60  s=uvcosα  α=arccos(ux2+uy2 vx2+vy2s)=arccos(32+52 102+6260)0.49 rad  A=α  =α π180   =0.49 π180   =28.072  =28.0725=28°421"
