Here are the solutions to the questions:

a) i) The distance and bearing of town D from school.

  1. Establish a coordinate system with the school at the origin.

    Let the school (S) be at $(0, 0)$.

  2. Determine the coordinates of Town A.

    Town A is 160 km North of the school.

    A=(0,160)A = (0, 160)
  3. Determine the coordinates of Town B.

    Town B is 100 km Westwards from Town A.

    B=(0−100,160)=(−100,160)B = (0 - 100, 160) = (-100, 160)
  4. Determine the coordinates of Town C.

    From Town B
