Guest Tie Guy Posted November 13, 2001 Share Posted November 13, 2001 Well, i got apox. 22.5, but that is based on the assumption that the lefft triangle is a 30*60*90 triangle, which i can't seem to prove at the moment. Wait, i just proved why it is NOT an 30*60*90 triangle, so forget everything i said, sorry. Link to comment Share on other sites More sharing options...
Guest dr_death Posted November 13, 2001 Share Posted November 13, 2001 i dont think it can be done! you would need to know the angle of at least one more corner or you would need to know the distance from where the line hits the base to one of the corners. without that info i dont think it can be acuratly done! i presume there is more to it that that but you havent wrote it down. if i am wrong please post the answer! sad as it may seem, i like maths Link to comment Share on other sites More sharing options...
Wraith 5 Posted November 13, 2001 Share Posted November 13, 2001 I agree with death... We need either another angle, or we need to know what Ah or Bh is Link to comment Share on other sites More sharing options...

Wraith 8 Posted November 13, 2001 Share Posted November 13, 2001 There IS A WAY..... i know the teacher who made it and Math is his life It is a big hobby for him... and knowing him... there is an answer. Not an easy one. but there is. Link to comment Share on other sites More sharing options...
EndSub Posted November 13, 2001 Share Posted November 13, 2001 First I used the Cosine Rule (Cos A = b^2 + c^2 - a^2\2.b.c) To work out B B = 53.1 Then I used the sine rule (Opp = Hyp * Sine A) to work out the opposite side (Opposite in the Left right-hand triangle relating to B) H = 28 * Sine 53.1 H = 22.39 Link to comment Share on other sites More sharing options...
AoErat Posted November 13, 2001 Share Posted November 13, 2001 Yep, EndSub is right. Gotta use trig guys. Link to comment Share on other sites More sharing options...

darthfergie Posted November 13, 2001 Share Posted November 13, 2001 MAN!!! YD!!! It was just basic trigenometry...(sin) (cos) (tan) REMEBER!!! Link to comment Share on other sites More sharing options...
Zygomaticus Posted November 13, 2001 Share Posted November 13, 2001 i agree with u but it can be done without trig too u can just use pythagorean theorum too by using a variable at the bottom like putting one side as x and the other side as 30-x Link to comment Share on other sites More sharing options...

Yeah i know and i think YD knows to... but this teacher is always wxplaining things with examples that are SO complex.... you dont get the whole picture of what it is all about.. so for us it is hard to get everything.

darthfergie Posted November 13, 2001 Share Posted November 13, 2001 I'm not so sure it is either... I have gotten top of the class in Math for the past...4 or 5 years...but I'd have to do the work myself...and I don't feel like doing that outside of school:D in school= Mind of a Genuis {or so everyone tells me} Out of school= 1+1=...dang didn't I see this somewhere before Link to comment Share on other sites More sharing options...
