Centrepoint tower in Sydney has a viewing platform located 268 metres above sea level. A tourist on the observation deck notices two boats on Sydney harbour. From the tourist's position:

The bearing of Boat A is $\displaystyle 130^{\circ}$ at an angle of depression of $\displaystyle 35^{\circ}$.

The bearing of Boat A is $\displaystyle 200^{\circ}$ at an angle of depression of $\displaystyle 42^{\circ}$.

Calculate the distance between the boats to the nearest metre.

The math most likely involves simply Ratio / Sine Law / Cosine Law calculations, so the math part shouldn't be a problem. The problem is drawing a proper diagram to model the question. All I've got so far is the attached. Can anyone help me with simply visualizing what the question asks? What does it even mean for the boat to be a bear of X degrees?
