What is the actual bearing of S25oE?
The 25o is at the south between the south and the east.
Between each cardinal point is 90o.
The angle from the east to the S25oE = 90 - 25 = 65
Bearing starts from the north. Hence the bearing of S25oE is from the north to the S25oE line.
Bearing = 90 + 65 = 155o
