    No because a right triangle has 90 degrees in it but since none of them have the measurement ABC is not a right triangle

    And what would AC have to be to make it a right triangle?

    To solve an SSS triangle: use The Law of Cosines first to calculate one of the angles. then use The Law of Cosines again to find another angle. and finally use angles of a triangle add to 180° to find the last angle.

    Pythagorean Theorem is the lesson this derives from? I don't even know The Law of Cosines..?

    sin = opposite over hypotenuse tan = opposite over adjacent cos = adjacent over hypotenuse

    you would use cosine =)

    I don't use that in my Geometry class? In fact I've never even been introduced to that.

    Except for the Pythagorean Theorem. \[a^2+b^2=c^2\]

    If a^2+b^2=c^2, its a right triangle.

    If they are less than it's acute. Greater than it's obtuse.

    So it would be radical 34?

    then yeah you would need the radical other than that it would be 5.83095189485^2
