Thank you
Sir angle between vector A and invers of vector B is 45 then angle between the A and B is 180 - theta i.e 180 -45 =135 *
Sir I got AB =1\√2 then answer is 45°
θ=0
sir answer for that last question is 45° ...i got it by graph but i m not getting that by that cosΘ formula

A•B=4. And (A)(B)=4√2. Cos theta=(A•B/AB)=1/√2
