here,
a)
the overall x displacement = 30 + bx - 21 - 82
- 150 = bx - 73
bx = -77 units
b)
and
the overall y displacement = 40 + 0 + cy - 55
-28 = cy - 15
cy = - 13 units
c)
the magnitude of total displacement , |D| = sqrt(150^2 + 28^2)
|D| = 152.6 units
d)
theta = arctan(-28 /(-150)) = 190.58 degree counterclockwise from +x axis
