given a vector is equal to a vector + b vector and R is equal to a is

1.	given a vector is equal to a vector + b vector and R is equal to a is equal to be the angle between a vector and b vector is
Answer» tion:The angle α which the RESULTANT R makes with A is GIVEN bytanα= A+BcosθBsinθ or COS(θ/2)sin(θ/2) = A+Bcosθ2Bsin(θ/2)cos(θ/2) which gives A+Bcosθ=2Bcos 2 ( 2θ )or A+B[2COS 2 ( 2θ )−1]=2Bcos 2 ( 2θ )A=B.thank you for question
