### Airplane Navigation Problem

#### Problem Statement:
A commuter airplane starts from an airport and takes the route shown in the figure below. The plane first flies to city A, located 175 km away in a direction 30.0° north of east. Next, it flies for 150 km 20.0° west of north, to city B. Finally, the plane flies 190 km due west, to city C. Find the location of city C relative to the location of the starting point.

#### Inputs:
- Distance covered during each leg of the trip.
- Angles indicating the direction of each leg of the trip relative to cardinal directions.

#### Inputs to Find:
- Distance: ______ km
- Angle: ______ ° west of north

#### Diagram Explanation:
The diagram represents the path taken by the airplane on an xy-coordinate system:

1. **Starting Point \( O \):** The initial point of the airplane.
2. **Segment \( \vec{a} \):** The airplane travels 175 km from point \( O \) to point \( A \) in a direction of 30.0° north of east.
   - Vector \( \vec{a} \): 
     - Magnitude: 175 km
     - Direction: 30.0° north of east
3. **Segment \( \vec{b} \):** From point \( A \), the airplane travels 150 km to point \( B \) in a direction of 20.0° west of north.
   - Vector \( \vec{b} \):
     - Magnitude: 150 km
     - Direction: 20.0° west of north
4. **Segment \( \vec{c} \):** From point \( B \), the airplane flies 190 km due west to point \( C \).
   - Vector \( \vec{c} \):
     - Magnitude: 190 km
     - Direction: Due west (270° from north)

#### Coordinate System:
- The x-axis represents the east-west direction (positive x towards east).
- The y-axis represents the north-south direction (positive y towards north).
- Angles are measured from the north direction (upward y-axis).

The coordinate positions to be found are \( x \) and \( y \) coordinates of city C relative to the starting point \( O \).

Important notations:
- \( \vec{R} \
