Let me see

anonymous · Answer

is this a right triangle?

babynini · Answer

em, I only have that information. From looking at the measurements I would assume no.

anonymous · Answer

if its not a right triangle then we can not use regular trig identies. so did you do law of sines or cosines?

babynini · Answer

Cosine :P

anonymous · Answer

ohh k i have an answer tell me one of your angles

anonymous · Answer

i got 41 as one angle. did you get the same?

babynini · Answer

Yup! :) Beta right? It comes out to 41 degrees 4'?

anonymous · Answer

so what were your other values then

babynini · Answer

Alpha: 64.277
Gamma: 23.212

anonymous · Answer

no

anonymous · Answer

i can tell you that isn't right just on the fact that they do not add up to 180

babynini · Answer

...it doesn't? It did on my calculator..

anonymous · Answer

64 + 23 + 41 = 180 ?

babynini · Answer

how much did it come to for you? perhaps becaues you don't have the exact numbers. Decimal places.

anonymous · Answer

i got the 23 and the by trig property of all angles = 180 means the other side = 115

babynini · Answer

I gotta go but please finish calculating it and i'll try and get back as soon as possible :)

babynini · Answer

ahh sorry I meant 115, 41, 23

anonymous · Answer

yeah that it

babynini · Answer

Okay, thanks!
