Question

A small angle is measured as 2 arc seconds. How many degrees or what portion of a degree does this represent?

Answer 1

Answer:

5.56 x 10⁻⁴ degree

Explanation:

1 degree = 60 arc minutes

1 minute = 60 arc second

1 degree = 60 x 60 = 3600 arc second .

3600 arc second = 1 degree

1 arc second = 1 / 3600 degree = 2.78 x 10⁻⁴  degree

2 arc second = 5.56 x 10⁻⁴ degree .
