    Basic Trig question

    Pick a tall structure (tree, house, billboard, etc.). Take a look at it at 3 points during the day (eg. 9 am, noon, 3 pm), and estimate the length of the shadow it makes at each time (stand on the side that has a shadow). Stand at the end of the shadow, and estimate the angle between the top of the structure and your viewpoint (90 is straight above you, 0 is same level as you, 45 is half way between, so 25 is about a of the way, etc.). Using the length of the shadow and the estimated angle, determine the height of the structure. Are your 3 answers similar? Post a message to the discussion group with your calculations and what you found.

    Any help on this problem would be more then appreciated! Thanks guys.
