Solve for the missing side lengths or angles using the Law of Cosines. Round your answers to one decimal place.
Missing Side: \(c=\sqrt{a^2+b^2-2ab\cdot\cos{C}}\)
Missing Angle: \(C=\cos^{-1}\left(\frac{a^2+b^2-c^2}{2ab}\right)\)
Where \(a\) and \(b\) are consecutive side lengths and \(C\) is the angle between them.
Result: --
