How do I solve this problem? Finding the resultant vector

[a321]

Homework Statement

Starting at the origin of coordinates, the following displacements are made in the xy-plane (that is, the displacements are coplanar): 60 mm in the +y-direction, 30 mm in the Ñx-direction, 40 mm at 150°, and 50 mm at 240°. Find the resultant displacement both graphically and algebraically.

Addition of vector components

The Attempt at a Solution

I tried to break it into components:
Ax=0
Bx=30
Cx=-34.6
Dx= -25

Ay=60, By=0, Cy=20, Dy=-43.3

However The answer is 97mm at 158°
How did they get this answer?

THANKS for your help!

hi a321! welcome to pf!

shouldn't B_x be minus 30 ? ​
