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.

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

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

It was just basic trigenometry...(sin) (cos) (tan)

REMEBER!!!:)

 

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. :D

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

;)
