Question

can some one help me with finding an angle between two vectors

Answer 1

\[u=<2,-4>, v=<3,-8\]

Answer 2

i already got here \[\cos \left( \theta \right) = \frac{ 6+32 }{ \sqrt{20}\times \sqrt{73}}\]

Answer 3

\[\theta = \cos^{-1} \frac{ 6+32 }{ \sqrt{20}x \sqrt{73} }\]

Answer 4

OMG THANK YOU SO MUCH

Answer 5

Welcome

Answer 6

Answer 7

do i multiply this by 360

Answer 8

That is probably in radians. You need to convert to degrees.
