I didn't touch sin, cos and tan because my teacher said there was a way without it ... So that is what I'm searching. And about the Grade ... What I and Wraith9 do is called MBO here. And this is the second time I do MBO, but just a whole different direction. I'm the oldest in my class with 21 (exept for Mark, but guys that don't come don't count) and the youngest is 16 or 17. But I must confess that the puzzle I gave you isn't the original form ... It was one step away from the original form ... wich is this: I made the triangle to get the height ... cause I need the height to get the Area (A) ... you know like in cm2. Cause in the end ... that's what I need to know ... A Link to comment Share on other sites More sharing options...
darthfergie Posted November 13, 2001 Share Posted November 13, 2001 Try extending the triangles...it is what my Math Mom said anyways... Like I said though...I can't think at home:) BTW, I think you should try the pythag...that is about the only thing I can think of at the moment:) Link to comment Share on other sites More sharing options...

But you need a 90 degree angle for that ... you give me one good one to use. And while we're still talking about school ... can somebody give me translation of 'La réussite sociale' ... I don't speak french. Link to comment Share on other sites More sharing options...

darthfergie Posted November 14, 2001 Share Posted November 14, 2001 Well YD...Here is my solution... 1) You work it all out how you think it could be done 2) Look in the back of Math book for answer (if it isn't there look for a similar problem)3) Re work it and see if you can figure out how they found that soultion 4) If you can't figure it out...ask someone at school tomorrow...maybe they know it so you can do it a few minutes or hours before math... 5) If you do figure it out...YOU GET IT CORRECT:D Link to comment Share on other sites More sharing options...

And let they get away with the reward ... can't have that And BTW ... I don't have school tomorrow 5) If you do figure it out...YOU GET IT CORRECT:D I'm almost there ....

darthfergie Posted November 14, 2001 Share Posted November 14, 2001 call some of the smarter members of your class if you must but since you don't have shool tomorrow (CURSE YOU;) ) Just do it the day AFTER tomorrow... Seriously I wouldn't spend more than 30 minutes on one problem MAX...unless it was for a major test then I don't know... Link to comment Share on other sites More sharing options...

Seriously ... the mars isn't what's on stake here ... it's my pride. If I don't solve this ... then I'm not worthy. If I haven't solved it by the end of tomorrow ... I'm gonna use the gonio way anyway ... But I know it can be done without. Link to comment Share on other sites More sharing options...
darthfergie Posted November 14, 2001 Share Posted November 14, 2001 Originally posted by krkode fergie what grade are u in? when did u do this stuff on geometry? Probably somewhere around christmas a few years ago... I remeber doing MUCh more complex things...the thing is I'm not in my school mode...in school mode I'm VERY serious and I can spit out answers like a calculator...but right now I'm in my stand by mode...No reason to get back into school mode once my brain has cooled down...it will just overstress my processor...

EndSub Posted November 14, 2001 Share Posted November 14, 2001 What Triangle do you need to know the area for? or do you need the area for the whole shape? and btw, krkode Trig Ratio's are not part Geometry....they get a topic all to them selfs Link to comment Share on other sites More sharing options...
Young David Posted November 14, 2001 Author Share Posted November 14, 2001 I alread have he awnser ... poped in my head last night I needed to have the area of the trapezium, but to calculate that I needed h as in the triangle (You can get the triangle from the trapezium) What I did is dividing AB in 'x' and '30-x' That way, you can calculate h like this I h² = 26² - x² II h² = 28² - (30-x)² So ... 26² - x² = 28² - (30-x)² 676 - x² = 784 - 900 + 60x - x² 792 = 60x x = 13,2 That makes h 22,4 and the total area of the trapezeum 336 cm² Link to comment Share on other sites More sharing options...

Young David Posted November 15, 2001 Author Share Posted November 15, 2001 It's the pride against Buitenweg that counts ... I could never confees to him I couldn't solve it. So I did everything in my powers to get the answer ... I guess I have enough powers The mars was yummie ... thank you guys ... Link to comment Share on other sites More sharing options...
