Answer:
Step-by-step explanation:
Check attachment for diagram
From the diagram, we can apply Pythagoras theorem to right angle triangle RPS
Then,
Tan θ = opposite / adjacent
Tan θ = 15 / 15
Tan θ = 1
θ = arcTan(1)
θ = 45°
The angle is between the east and south
Then, the bearing of 45°S of east.
The direction is also β
Where
β + θ = 360°
β + 45 = 360°
β = 360 - 45
β = 315°
