On your sketch label at least the components of R , the angle from the + x axis, θ R , and an additional convenient angle to help get θ R . Calculate the magnitude of R & the standard angle θ R in degrees & radians. _ ____________ R = √ 45.2 2 + 45.1 2 = 63.9 θ R = tan1 (R y / R x ) = tan1 ( 0.998 ) = 44.9º 44.9º = 44.9º x ( π rad / 180º ) = 0.784 rad  R  = ___ 63.9 (64) _________ N θ R = ___ 44.9 (45) _______ º θ R = ____0.784 (0.78) ____ rad...
