A) Using a well labelled sketch diagram, calculate the bearing and the distance of Z from Y. b) Calculate the bearing of Z from Y.

Let Y be the origin $(0,0)$.
X is 200m to the south of Y, so X is at $(0, -200)$.
Z is 200m from X on a bearing of $310^\circ$.

From X, the direction to Y is North ($0^\circ$).
The bearing of Z from X is $310^\circ$.
The angle between the North line (XY) and the
