Best ResponseYou've already chosen the best response.1I thought those are 306090 Triangles, so the hypotenuse would be twice the short side.

Best ResponseYou've already chosen the best response.1the perimeter is 29 4+5+10+8 = 27, not 29

Best ResponseYou've already chosen the best response.1why would you think its a 306090? nothing indicates to me that that is the case

Best ResponseYou've already chosen the best response.1hmm, all i know at the moment is that 10 and 8 dont work out for the stated perimeter. do you agree?

Best ResponseYou've already chosen the best response.1im wondering if we can use them in a general sense tho, i havent got a clear approach yet.

Best ResponseYou've already chosen the best response.1other than assuming a 30=6090 what else are you thinking of?

Best ResponseYou've already chosen the best response.1I'm wondering if we can use this theorem: An angle bisector of a triangle divides the opposite side into two segments whose lengths are proportional to the lengths of the two other sides.

Best ResponseYou've already chosen the best response.1sounds reasonable: so the ratio is 5:4, therefore 5k + 4k + 9 = 29 what is k?

Best ResponseYou've already chosen the best response.1i was working out something like sin(a')/5 = sin(c)/(ad) sin(a')/4 = sin(b)/(ad) (ad) sin(a') = 5sin(c) (ad) sin(a') = 4sin(b) 5 sin(c) = 4 sin(b) sin(b)/4 = sin(c)/5 = sin(a)/9

Best ResponseYou've already chosen the best response.1(5(20)+ 4(20) + 81)/9 (180 + 81)/9 261/9 = 29 of course
