Question

See the above figure and answer the following question.

What would be the value of angle AOB?

Options

• 40°

• 20°

• 10°

• 140°

Answer 1

40°

Explanation:

In the given figure, the angle AOB represents the angle formed between the Prime Meridian (which runs vertically in the middle) and the 40° Meridian (represented as the meridian at an angle of 40° from the Prime Meridian).

Since meridians are angular divisions of the Earth's surface and the difference between the two meridians is 40°, the angle between them, angle AOB, would be 40°.
