Summer School Final Assessment

The diagram, not drawn to scale, shows a vertical flagpole, FT, with its foot, F, on the horizontal plane EFG. ET and GT are wires which support the flagpole

in its position. The angle of elevation of T from G is 55 degrees, and FG = 6 m. Calculate, giving your answer correct to 3 significant figures the height, FT, of the flagpole.
