      There's a problem with this question meaning that by using different methods one gets different answers. All of the angles in that triangle don't actually add up to 180 degrees if i remember correctly. What you are doing may be "correct" as such, and different than the solution you are looking at.

      That 168.35 refers to the correct length of the line HP when the question is corrected.
