Answer:

90 degrees

Explanation:

Answer 2

When we look at the full moon the angle subtended by the eye is about 1/2°

i.e. θ = 31 arcminutes = 1/2°

Explanation:

• The full moon makes an angle of 360° in the sky.
• 1° can be divided into 60 arcminutes. An arcminute can also be divided into 60 arcseconds.
• The diameter of the full moon makes an angle of 1/2° or 31 arcmin.
• Therefore astronomers say that the Moon subtends an angle of 31 arcmin.
• When we look at the full moon the angle subtended by the eye is about 1/2°

• i.e. θ = 31 arcminutes = 1/2°
