Answer: 1) Angular separation equals 0.0000031 degrees
2) Angular separation in arc -seconds equals 0.011156"
Explanation:
For 2 stars separated by a distance 'S' and at a distance 'D' from the earth the angular separation in radians is given

Applying values we get

Now we know that 'π' radians equals 180 degrees thus the above value in degrees shall be equal to

2)
The angular separation in arc- seconds is given by
