Ashley's parents are throwing a graduation party and are renting a 40ft x 80ft tent for their backyard. The base of the tent is supported 7ft above the ground by the poles and then roped stakes are used for support. The ropes make a 45 degree angle with the ground. What are the dimensions of the rectangle formed by the stakes on the ground? Round to the nearest foot.

    no i think it looks like this because that other drawing cant make 45degrees to ground|dw:1438499157690:dw|

    yea i realized awhile after i drawn it, because the both sides has to be same to be a 45/45/90 triangle, but the height is 7 and length is 20 so it cant be right

    |dw:1438531399144:dw| we need "special" knowledge about how to put up the tent to start with ... it may even need to be like this.

    the ropes may need to be pulled tight ... diagonally to the corners to provide a better tension for the setup ... otherwise it is weak directionally

    a very ambiguous question

    @amistre64 That looks like a weird tent, maybe we also need to consider how typically a tent looks like, also your 3D imaginations is just amazing, I can never imagine geometrically in 3d so good It could be possible, but when I imagine a tent I think of it like a triangular prism

    well, a party tent is generally of a different shape than a camping tent ... even these days the damping tents are more domes then triangles anymore.

    the dimensions suggest that its not going to be dome-like :) so either way the "rectangular base" is being supported. to determine the best placement of the tension ropes, you have to think like an engineer tho

    |dw:1438532450295:dw| with this setup, there is no support in this direction

    i build tents like this while im in the army|dw:1438532492078:dw|goes very little to the front direction but the stakes are punched in deep

    but then there will be an ambiguity of where the rope is connected to the tent at, we can't just take it the midpoint conviniently

    i say if we pound the poles in deep enough, then we dont even need the ropes ;)

    the ropes are actually to keep the clothes from sagging

    It's just amazing how even simple questions can have many interpretations, we need to think like a 10th grader for this

    In any case, your 2nd figure will do @saseal, even if u rotate it the rectangle will rotate with it, keeping it's area the same, because the prism one is totally off the board now and that is the only shape one would intuitively think of right off the start

    yea cause you have maintain that theres a 45degree triangle and that triangle could swing anywhere 7ft outside of that area and still but a 45/45/90, but the area changes a lot
