AOD = 180 - BOC

 

AOD = 3.5 BOC    or   BOC = AOD/3.5    sub in to top equation

 

AOD = 180 - AOD/3.5

AOD = 140 DEGREES

Hi guest. 

 

I really like your solution, but I don't think AOD = 180 - BOC. 

Instead, I think we need to start with the fact that AOC = 90 and COA = 90 since lines are perpendicular.
