Answer:
Answer is 1 degree.
Explanation:
W MAP stands for Wilkinson Anisotropy Probe which was working from 2001 to 2010 .It usually measured the temperature differences.Big Bang was a partnership with NASA and Princeton University. So if universe is geometrically flat we should observed that temperate between patches are separated by 1 degree.Because Universe is oval shape and contain 360 angular shape but if it goes flat we can see the patches at very low distance that is 1 degree.
