Question: Confirm whether the leaning tower of pisa is leaning, and if the lean is changing (between any two random days). Only tools given: Ability to measure vertical angles and fixed length rod (say 2m). Supposed to use basic geometry and trig. Made my head hurt for real trying to figure that out.
