3rd eddition:

Dr = 54.0 m @ -42.0^o

Dr_y = Dr sin(q_r) = (54.0 m) sin(-42.0^o) = -36.1 m

D r_x = Dr cos(q_r) = (54.0 m) cos(-42.0^o) =  40.1 m

Dr = [(40.1)x + ( -36.1)y] m

2nd eddition:

Dr = 65.0 m @ -40.0^o

Dr_y = Dr sin(q_r) = (65.0 m) sin(-40.0^o) = -41.8 m

D r_x = Dr cos(q_r) = (65.0 m) cos(-40.0^o) =  49.8 m

Dr = [(49.8)x + (-41.8)y] m
