When you're considering it from a Newman projection that's not the case. When you look down the C-C bond the 3 hydrogen atoms are at 120 degrees from one another. Remember this is NOT the bond angle, this is the three of them arranged essentially around a circle in a Y or ⅄ shape. If a circle has 360 degrees then 360/3 = 120.
