A tall radio mast is attached by several cables. The length of each cable is \(30\, \mathrm{m}\) and all cables are attached \(2\, \mathrm{m}\) under the top of the mast. The second end of the cable is anchored to the ground. The cable is in the height \(6\, \mathrm{m}\) if measured directly above the point which is in the distance \(8\, \mathrm{m}\) from the point where the cable is anchored to the ground. Find the height of the mast.
\(20\, \mathrm{m}\)
\(24\, \mathrm{m}\)
\(22.5\, \mathrm{m}\)
\(24.5\, \mathrm{m}\)
