do you know the cosine rule?

Can you tell me it again? I forgot it

adjacent over hypotenuse

welcome

"on the right side of the equation"?

are we good to go?

I'm trying to solve. Just a sec

sure :)

I keep getting error when trying to solve using my TI83

hmm, let's see what i get..just a sec

angle A = 79.193 degrees :)

Thank you! So the final answer is 79.193?

no, you'll have to check the other angles to be sure which one is the largest :)

Oh o.k. So I use the same formula?

Sounds good

:)

sorry i made a mistake somewhere,
A=46.567
B=104.478
C=28.955

Oh :/ Was it the formula or a mistake in the arithmetic?

Yes, I used the formula :) So obviously B is the largest angle

:) so u got the largest angle, what are u supposed to do with it?

Take cosine. So just a sec... -.2500?

yay! :) our work is done here :)

And I couldn't have done it without you! Thank you so much I really appreciate it :)

anytime :) you're welcome :)
