Finding the interior angles of a triangle when given the sides lengths of 2,3,4

[natester4915]

Hi,
I have a triangle with three sides with the lengths of 2,3,4. How do I find the interior angles? I tried using the Law of Sine and the fact that the sum of the interior angles add up to 180 deg but i didn't make it very far.
Thanks for the help.

You may wish to consider the Law of Cosines. This always pins down one of the angles.
