Question

Find the bearing of the London airport from Manchester airport if Manchester airport is on a bearing of 330° from a London airport.

Answer 1

The bearing of the London airport from Manchester airport is 150°, calculated by subtracting 180° from the given bearing of Manchester from London, which is 330°.

Step-by-step explanation:

The question involves finding the bearing of the London airport from Manchester airport, given that Manchester airport is on a bearing of 330° from a London airport. Bearings are always measured in degrees, starting from true north and moving clockwise. In this case, the bearing provided is 330°, therefore, to find the bearing from Manchester back to London, we must think about the opposite direction.

To calculate the reverse bearing, add or subtract 180°. If the angle is less than 180°, you would add 180°, and if it is more than 180°, you subtract 180°. Since 330° is greater than 180°, we subtract 180° to find the reverse bearing. Hence, the bearing of the London airport from Manchester airport is 330° - 180° = 150°

Answer 2

To find the bearing of London airport from Manchester airport, with Manchester airport on a bearing of 330° from London airport, subtract 330° from 360° to get 30°.

Step-by-step explanation:

The question relates to finding the bearing of London airport from Manchester airport, given that the bearing of Manchester from London is 330°. A bearing is an angle measured in degrees in a clockwise direction from the north line. To find the opposite bearing, you would subtract the given bearing from 360° if it is greater than 180°, or add 180° to it if it is less than 180°. In this case, since 330° is greater than 180°, the opposite bearing can be found by subtracting 330° from 360°.

The calculation: 360° - 330° = 30°. Therefore, the bearing of London airport from Manchester airport is 30°.
