```							If we assume vectors as X, then the magnitude of the resultant vector is also X. This is mentioned in the question itself.To find the resultant vector, we have an equation: R2 = A2+B2+2ABcosθApplying the above formula gives: X2 = X2+X2+2XXcosθX2 = 2X2+2X2cosθ-X2 = 2X2cosθ-1/2 = cosθTherefore, θ = cos-1(-1/2) = 120o ANSWER: ANGLE BETWEEN 2 VECTORS IS 120 DEGREE
