**Problem Description:**

A commuter airplane starts from an airport and takes the route shown in the diagram 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 at 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.

**Diagram Explanation:**

- The diagram includes a coordinate grid with the y-axis representing the north direction and the x-axis representing the east direction.

- Starting point \( O \) is at the origin of this grid.

- The first leg of the journey, vector \( \vec{A} \), is a line from \( O \) heading 30.0° north of east for a distance of 175 km.

- The second leg of the journey, vector \( \vec{B} \), is a line beginning at city \( A \), heading 150 km at 20.0° west of north to city \( B \).

- The final leg, vector \( \vec{C} \), is a due west line from city \( B \) to city \( C \) covering 190 km.

- The diagram also includes a compass rose indicating cardinal directions (N, E, S, W) and angles corresponding to vector directions.

- Vector \( \vec{R} \) is shown as the resultant vector from \( O \) to \( C \).

**Inputs:**

- Distance: _______ km

- Angle: _______° west of north

Your goal is to calculate the straight-line distance and angle from the starting point to city \( C \).
