    Smile A possible alternative to the Law of Cosines

    Is there an alternative way of finding the third side of a triangle when you have SAS without using Law of Cosines?

    Thank you!
    I can't view the image you attached but I did try drawing a figure on a coordinate plane and it definitely helped!

    Strange that, it was uploaded from the other machine, and displayed correctly for me, but viewing from this machine the link is broken and the image is no longer present in the upload manager?! I will have to sort that out in the morning when I can get at the other machine.

    I have noticed odd behaviour of attached image files in other posts (mainly getting them to dispay rather than just appear as a link).
