I don't know where your diagram comes from but textbooks (for example Housecroft&Sharpe, Inorganic Chemistry) as well as wikipedia (http://en.wikipedia.org/wiki/Nitric_acid#/media/File:Nitric-acid-2D-dimensions.png) say that the angle HON is 102°, NOT 90°.
Click at the wiki link and find the information you need. Cheers.

A(should be Å) stands for angstrom (unit of lenght - after the  Swedish physicist Anders Jonas Ångström), not for Armstrong
