Front

In a traverse, the deflection angle is the difference between:

Back

Included angle and 180°

Answer explanation

Deflection angle = 180° – Included angle

Front

Front

What is the typical length range of a trough compass?

Back

8 to 15 cm

Answer explanation

Front

A line was drawn to a magnetic bearing of 252° on an old map when the declination was 3°W. To what bearing should it be set now if the present declination is 8°E?

Back

241°

Answer explanation

Old magnetic bearing = 252°. Old declination = 3°W → True bearing = 252° − 3° = 249°. Present declination = 8°E → New magnetic bearing = True bearing − 8° = 241°.
