Best ResponseYou've already chosen the best response.1ohh i like pi/4 angle the angles become congruent and 2 sides become equal :P

Best ResponseYou've already chosen the best response.0:D I set up tan45=a/3

Best ResponseYou've already chosen the best response.0since it's a 454590 triangle a and b are both 3

Best ResponseYou've already chosen the best response.0so 3^2+3^2=c^2, 9+9=c^2, 18=c^2 i'm not sure if we need to get square root of 18

Best ResponseYou've already chosen the best response.1ok, lets use a trig function then find sin A or sin B

Best ResponseYou've already chosen the best response.0so sin(45)=3/c, c=3*sin45 which is 2.12

Best ResponseYou've already chosen the best response.1you can keep it as \(3/ \sqrt 2\)

Best ResponseYou've already chosen the best response.0where did we get the 3/sqrt of 2 from? lol

Best ResponseYou've already chosen the best response.1because it is mentioned, "no decimals"

Best ResponseYou've already chosen the best response.1sin 45 = 1/\(\sqrt 2\) 3 sin 45 = 3/\(\sqrt 2\)

Best ResponseYou've already chosen the best response.0sin of 45 =sqrt(2)/2..

Best ResponseYou've already chosen the best response.0hmm a little confused why we are multiplying by 2 :/

hartnn

Best ResponseYou've already chosen the best response.1we're braking 2 as \(\sqrt 2 \times \sqrt 2 \) if thats confusing you, you can keep the answer as \(3\sqrt 2/2 \) also

Best ResponseYou've already chosen the best response.0so the length of a should be 3,

Best ResponseYou've already chosen the best response.1length of a was always 3... i though we were talking about length of c

Best ResponseYou've already chosen the best response.0Yea I'm just clarifying :)

anonymous

Best ResponseYou've already chosen the best response.0and length of c=3sqrt(2)/2?

anonymous

Best ResponseYou've already chosen the best response.0for some reason it's saying that c isn't correct

Best ResponseYou've already chosen the best response.1try 3/ \(\sqrt 2\) once?

Best ResponseYou've already chosen the best response.0so since I got it wrong it gave me the same problem expect a=6

hartnn

Best ResponseYou've already chosen the best response.1oh wait! sin A = a/c c = a/ sin A = 3/ sin 45 = 3 sqrt 2 :P

anonymous

Best ResponseYou've already chosen the best response.0and b would just equal 6 because they are 454590

Best ResponseYou've already chosen the best response.0yay :D it's right thank you

Best ResponseYou've already chosen the best response.0Since it is an isosceles triangle and b = 3, then a = 3 and the hypotenuse= 3sqrt2 and both A & B are pi/4 radians
