```							Dear Student,Resultant a vector will be= sqroot(3.2^2 + 1.6^2)                                = 3.5777Resultant b vector will be = sqroot(0.5^2 + 4.5^2)                                    = 4.527Angle of a vector making woth horizontal, costhetha = 3.2/3.577 = 0.89thetha = 26.5 degree. Angle of b vector making with horizontal, costhetha = 0.5/4.527 = 0.1004thetha = 84 degree.Angle between a and b vector = 84 – 26.5 = 57.5 degree.
