Help with inclination angle

  1. Apr 28, 2009 #1
    I've got a lab. And the deal is, you're measuring certain things on various galaxies and eventually calculating the Tully-Fischer relation. Anyways, part of it is calculating an inclination angle to all of the galaxies measured. And I'm stuck with this. I have the major and minor axis dimensions to each galaxy but not really much else. Have the magnitude of the flux through each of them, but don't think that would help. I'm somewhat bad at geometrical relations, can anyone help clue me in on getting inclination angles with just the dimensions of the galaxy and assuming that they're intrinsically circular systems and infinitely thin disks?

    Nevermind, had it right beforehand. Excel just spits out angles in radians, got confused, hehe.
