Should be simple SSS law of Cosinies issue.

Can someone please help me solve the measures of angles in a triangle with sides of length 105, 33, and 138? I keep getting ridiculous answers from excel and r. Thanks for your help!

What answers are you getting? Maybe they're right! BTW: 105+33=138 so this isn't really a triangle. It's just a line!!

You're right. And I guess I was right with the ridiculous answers. I was getting 0,0, and pi... Now let's check that ruler... Thanks for the help!
