What displacement must be added to a 50 cm displacement in the +x-direction to give a resultant displacement

Question

of 85 cm at 25°?

Answer 1

well in the x direction it is 85 cos 25 - 50
and in the y direction it is 85 sin 25

Answer 2

50 + D = 85[25o].
D = 85[25] - 50 = 77+35.9i - 50 = 27 + 35.9i = 44.9cm[53.1o] = Displacement added.
