Explanation / Answer

One light year is:

9.461 × 1012 kilometers

We have 200 light years, so the distance to the stars is actually:

200 * (9.461 x 1012 km)

To get the degree, use tan:

tan((90 * 107 km)/(200 * (9.461 x 1012 km)))

8.30142  x 10-9 radians

This gives us the degree in radians, so we just convert this to degrees for our sake by multiplying by 180/pi.

4.75636 x 10-7 degrees

1 degree =3600 arc seconds

4.75636 x 10-7 degrees = 1.71229 x 10-3 arc seconds
