1. The problem statement, all variables and given/known data You are driving into St.Louis Missouri, and in the distance you see the famous Gateway-to-the-west arch. This monument rises to a height of 192 m. You estimate your line of sight with the top of the arch to be 2.0 degrees above the horizontal. Approximately how far (In Kilometers) are you from the base of the arch. Height= 192 m Angle= 2.0 degrees 2. Relevant equations[/b Definition of Cos, Sin, and Tan or the inverse trigonometric functions I have no clue on what I should do. This is what I did. H adjacent= 192/tan(2.0)= 5498m and then I converted it to KM and I got 8848 km. This answer is way off, and I know I'm doing something wrong.
