a commuter plane starts from an airport and takes the route whereby it starts to city,located 175km away in a directiin 30egrees north of east of east. Next, it flies for 150 km 20degrees west of north,to city b.finally, the plane flies 190kmdue west,to city c. Find the location of city c relative to the location of the starting point.

1. Add the three displacement vectors, to get the net displacement, D1 + D2 + D3.

D1 = 151.6 i + 87.5 j
D2 = -51.3 i + 141.0 j
D3 = -190 i

i is a unit vector East and j is a unit vector North.
