my questrion is on step $3,$ when i do D$1=$actrantan$(0\mathrm{.}0145903)/$cos$(0\mathrm{.}8447)=32\mathrm{.}84$ how did you get this value becoz the value i get when appliying same method i get $0\mathrm{.}025831$ how did you get $32\mathrm{.}84$ and on the azimuth please explain which values were used to get the final azimuth.

thank you
