A few minutes later, the angle of elevation to the same balloon is 38, If the observer is standing 60 feet away from the landing point of the balloon, what distance has the balloon descended between sightings? (Round your answer to the nearest tenth.) 2. A flagpole located at the top of a building is 30 feet long.
