A right-angled trapezoid EFGH EFGH\,EFGH is shown. The vertices are labeled EEE (top-left), FFF (bottom-left), GGG (bottom-right), and HHH (top-right). The base FG FG\,FG is horizontal and labeled 18 m. The side EF EF\,EF is vertical and labeled 15 m. The side HG HG\,HG is vertical and labeled 21 m. Right-angle symbols are shown at vertices F F\,F and GGG, indicating that EF⊥FG EF \perp FG\,EF⊥FG and HG⊥FGHG \perp FGHG⊥FG. The angle HEF HEF\,HEF is the interior angle at vertex E E\,E between sides EF EF\,EF and EHEHEH.
Work out the size of angle HEFHEFHEF. Give your answer to 1 decimal place.
